Leviticus 18
Berean Study Bible

Unlawful Sexual Relations

Then the LORD said to Moses,

God spoke with covenant authority through Moses, whom He appointed to teach Israel His holy will. As Israel camped in the wilderness after leaving Egypt, the Lord was forming them into a people distinct from Egypt and Canaan. The commands that follow govern sexual conduct and protect marriage, family, human dignity, and worship from the corrupt practices associated with surrounding nations.

Exo 6:1 But the LORD said to Moses, “Now you will see what I will do…
Num 1:1 On the first day of the second month of the second year…
Lev 1:1 Then the LORD called to Moses and spoke to him…

“Speak to the Israelites

Moses delivered God’s commands to the covenant people redeemed from Egypt and gathered at Sinai. Israel’s calling as a holy nation required conduct distinct from the surrounding peoples, especially in matters of worship, family, and sexual faithfulness.

Lev 1:2 “Speak to the Israelites and tell them: When any of you”…
Num 15:2 Speak to the Israelites and tell them: …
Lev 4:2 Tell the Israelites to do as follows with one who sins…

and tell them:

God’s revealed will was to be communicated plainly and preserved among every generation. Moses served as the appointed mediator of the Law, bearing responsibility to declare without alteration what the Lord commanded. Keep the exact same text, except to include the meaning of a name or place, only if it is included in The directive to “tell them” emphasizes the role of Moses as a prophet and leader. It highlights the importance of verbal communication in transmitting God's laws and decrees. In the ancient Near Eastern context, oral tradition was a primary means of preserving and conveying important information. This phrase also underscores the responsibility of leaders to faithfully communicate God's word to His people, a theme that is echoed throughout Scripture (Deuteronomy 6:6-9, 2 Timothy 4:2).

Jer 1:17 Get yourself ready. Stand up and tell them everything…
Num 15:38 Speak to the Israelites and tell them that…
Exo 25:2 “Tell the Israelites to bring Me an offering”…

I am the LORD your God.

The covenant name of God grounded every command in His redeeming authority and faithful relationship with Israel. The Lord who brought them out of Egypt had the right to order their lives, and His holiness set the standard for their obedience.

Lev 19:4 Do not turn to idols or make for yourselves molten gods.…
Exo 20:2 I am the LORD your God, who brought you out…
Deu 5:6 I am the LORD your God, who brought you out…

You must not follow the practices of the land of Egypt, where you used to live,

Israel’s long residence in Egypt had placed the nation amid pervasive idolatry and a culture ordered around false gods. Though the LORD had redeemed them from slavery, redemption required a decisive break with the life from which He had delivered them. Egypt was not to define Israel’s worship, morality, or identity. God’s people were to remember that they belonged to Him, not to the world from which He had saved them.

Ezk 20:7-8 And I said to them: ‘Each of you must throw away…
Jos 24:14 Now, therefore, fear the LORD and serve Him…
Ezk 20:18-19 In the wilderness I said to their children: ‘Do not walk…

and you must not follow the practices of the land of Canaan, into which I am bringing you.

Canaan’s inhabitants practiced idolatry, sexual immorality, divination, and child sacrifice in connection with their gods. Israel would enter the land as the LORD’s covenant people, not as another nation ready to absorb its religion and values. The coming conquest would bring God’s judgment upon Canaan’s entrenched wickedness, while also testing whether Israel would obey the God who gave them the land. Deuteronomy 12:29–31 repeats the warning not to learn the ways by which the Canaanites served their gods.

Deu 12:30-31 be careful not to be ensnared by their ways…
Deu 18:9 When you enter the land that the LORD your God gives you,…
Jos 23:7 So you are not to associate with these nations that remain…

You must not walk in their customs.

Israel was forbidden to adopt the pattern of life found either in Egypt behind them or Canaan before them. Their conduct was to be shaped by the LORD’s commands, which follow in the laws concerning marriage, sexuality, family, and worship. Holiness involved more than rejecting isolated acts; it required a people whose daily life reflected the character of their holy God. Leviticus 20:26 states this calling plainly: “You are to be holy to Me because I, the LORD, am holy.” Christ perfectly fulfilled this holy obedience, and those redeemed by Him are called to walk no longer according to the world’s pattern but according to the Spirit.

2Ki 17:8 and walked in the customs of the nations…
Jer 10:2 This is what the LORD says: “Do not learn the ways…
Eph 4:17 So I tell you this, and insist on it in the Lord,…

You are to practice My judgments

Israel’s conduct was to be governed by the LORD’s revealed will rather than by the corrupt patterns of Egypt, from which He had delivered them, or Canaan, into which He was bringing them. The commands of Leviticus 18 guarded marriage, family, worship, and public morality, preserving a people holy to God.

Ezk 20:11 And I gave them My statutes and made known to them…
Deu 4:1 Hear now, O Israel, the statutes and ordinances…
1Ki 8:58 May He incline our hearts to Himself, to walk in His ways…

and keep My statutes

The covenant required more than knowledge or occasional compliance. God’s people were to treasure His commands and order their households and community life around them. Holiness involved faithful obedience in ordinary life as well as in worship.

Deu 4:40 Keep His statutes and commandments, which I am giving you…
Deu 11:1 You shall therefore love the LORD your God…
Ezk 36:27 And I will put My Spirit within you and cause you…

by walking in them.

Obedience was to be a continuing manner of life. To walk in God’s ways meant to live under His rule with persevering faithfulness. Enoch and Noah walked with God, and believers are called to walk by the Spirit in the new life Christ gives.

Ezk 11:20 so that they may follow My statutes, keep My ordinances,…
Deu 5:33 You must walk in all the ways that the LORD your God…
Psa 119:1 Blessed are those whose way is blameless,…

I am the LORD your God.

The authority behind every command rests in the identity of the covenant God who redeemed Israel and claimed them as His own. The LORD’s holiness, faithfulness, and saving mercy formed the foundation for Israel’s obedience. Jesus fulfills the law and calls those who love Him to keep His commands.

Lev 20:7 Consecrate yourselves, therefore, and be holy,…
Deu 5:6 I am the LORD your God, who brought you out…
Exo 20:2 I am the LORD your God, who brought you out…

Keep My statutes and My judgments,

Israel was called to order every part of life under the covenant commands given by the Lord at Sinai. These instructions governed worship, family life, justice, sexuality, and treatment of others, distinguishing God’s people from Egypt, Canaan, and every surrounding nation. Obedience was to arise from devotion to the Lord, loving Him with the whole heart, soul, and strength.

Ezk 18:9 He follows My statutes and faithfully keeps My ordinances.…
1Ki 2:3 And keep the charge of the LORD your God to walk in His ways…
Deu 11:1 You shall therefore love the LORD your God…

for the man who does these things will live by them.

Faithful obedience brought covenant life: preservation, blessing, and continued enjoyment of the land God promised to Israel. Sin brought the opposite—defilement, judgment, and death. The law also revealed humanity’s inability to attain righteousness through personal obedience, since all have sinned. Paul cites these words to show that the law demands doing, while eternal life is received through faith in Christ, who fulfilled the law perfectly and bore its curse for His people.

Ezk 20:11 And I gave them My statutes and made known to them…
Rom 10:5 For concerning the righteousness that is by the law,…
Gal 3:12 The law, however, is not based on faith;…

I am the LORD.

The authority behind every command is the covenant God who delivered Israel from Egypt and made them His own possession. His statutes reflected His holy character and were therefore neither arbitrary nor optional. The Lord’s repeated declaration called Israel to trust, reverence, and obey the God whose name reveals His eternal, self-existent faithfulness.

Ezk 20:12 I also gave them My Sabbaths as a sign between us,…
Exo 20:2 I am the LORD your God, who brought you out…
Exo 6:7 I will take you as My own people, and I will be your God.…

None of you are to approach

God holds every member of Israel accountable for honoring His holy boundaries. Sexual sin begins with willing intent, not merely outward action.

1Co 7:1 It is good to abstain from sexual relations.…
1Th 4:3-5 For it is God’s will that you should be holy:…
Heb 13:4 Marriage should be honored by all and the marriage bed…

any close relative

Family relationships were to be guarded as gifts of God, not exploited for personal desire. The following laws identify prohibited unions and preserve the order, trust, and protection necessary within the household.

Deu 27:22 Cursed is he who sleeps with his sister,…
Deu 27:20 Cursed is he who sleeps with his father’s wife……
1Co 5:1 It is actually reported that there is sexual immorality…

to have sexual relations.

Incest defiles those involved and violates God’s design for marriage and family. Israel was not to imitate the immoral practices associated with Egypt or Canaan but to live as a people set apart for the Lord.

1Co 6:18 Flee from sexual immorality. Every other sin…
Eph 5:3 But among you, as is proper among the saints,…
Col 3:5 Put to death, therefore, the components…

I am the LORD.

The command rests on the authority and holiness of Israel’s covenant God. Obedience reflected loyalty to the One who had redeemed them and called them to be holy as He is holy.

Exo 20:2 I am the LORD your God, who brought you out…
Exo 6:2 God also told Moses, “I am the LORD.
Isa 45:5 I am the LORD, and there is no other; there is no God but Me…

You must not expose the nakedness of your father

Sexual union with a father’s wife dishonors the father and violates the order God established for the household. Israel was not to imitate the sexual practices of Egypt or Canaan, where such boundaries were disregarded.

Lev 20:11 If a man lies with his father’s wife,…
Gen 49:4 Uncontrolled as the waters, you will no longer excel,…
Gen 9:22-23 And Ham, the father of Canaan,…

by having sexual relations with your mother.

Incest with one’s mother profanes a relationship marked by nurture, authority, and honor. The sin brings disorder into the family and defilement into the covenant community.

Lev 20:14 If a man marries both a woman and her mother,…
Deu 22:30 A man is not to marry his father’s wife…
1Co 5:1 It is actually reported that there is sexual immorality…

She is your mother;

A mother’s God-given place demands honor, as required in the fifth commandment. Her identity as mother establishes a permanent boundary that sexual desire must never cross.

Exo 20:12 Honor your father and mother, so that your days may be long…
Deu 5:16 Honor your father and your mother, as the LORD your God…
Pro 23:22 Listen to your father who gave you life,…

you must not have sexual relations with her.

The direct prohibition leaves no room for exception. God calls His people to holiness in their closest relationships, and the New Testament likewise condemns sexual union with a father’s wife as grievous sin (1 Corinthians 5:1).

Deu 27:20 Cursed is he who sleeps with his father’s wife……
Gen 35:22 While Israel was living in that region, Reuben went in…
2Sa 16:21-22 Sleep with your father’s concubines, whom he has left…

You must not have sexual relations with your father’s wife;

God protects the order and sanctity of the household by forbidding a son to take the wife of his father, including a stepmother. Such conduct violates the father’s marriage covenant and corrupts the family relationships God established. Reuben’s sin with Bilhah brought lasting consequences upon his standing in Jacob’s family (Genesis 35:22; 49:3–4). Paul likewise condemned a similar offense among the Corinthians as scandalous even by pagan standards and called the church to exercise holiness (1 Corinthians 5:1–5).

Deu 22:30 A man is not to marry his father’s wife…
Lev 20:11 If a man lies with his father’s wife,…
1Co 5:1 It is actually reported that there is sexual immorality…

it would dishonor your father.

Sexual sin against a father’s wife publicly disgraces the father and treats his marital union with contempt. Israel was called to honor father and mother and to reflect God’s holiness in private conduct as well as public life (Exodus 20:12; Leviticus 19:2). The command guards family integrity, restrains destructive desire, and upholds the faithfulness required of God’s people.

Deu 27:20 Cursed is he who sleeps with his father’s wife……
Gen 49:4 Uncontrolled as the waters, you will no longer excel,…
1Ch 5:1 These were the sons of Reuben the firstborn of Israel.…

You must not have sexual relations with your sister,

God guards the family as a place of covenant faithfulness, protection, and ordered relationships. Sexual union within a sibling relationship violates the boundaries He established for kinship and brings corruption into a bond meant to reflect mutual care and honor. Leviticus 20:17 confirms the seriousness of this sin by assigning severe covenant judgment to it.

Ezk 22:11 One man commits an abomination with his neighbor’s wife;…
2Sa 13:1-14 After some time, David’s son Amnon fell in love…
Gen 34:1-7 Now Dinah, the daughter Leah had borne to Jacob,…

either your father’s daughter or your mother’s daughter,

The prohibition includes both full sisters and half-sisters. Earlier patriarchal practices, such as Abraham’s marriage to Sarah, his half-sister, occurred before the Mosaic Law gave Israel these specific boundaries; Israel was now called to live under God’s revealed holiness. Amnon’s assault of his half-sister Tamar later showed the devastating personal and dynastic consequences of disregarding God’s order (2 Samuel 13:1–19).

Lev 20:17 If a man marries his sister, whether the daughter of his…
Deu 27:22 Cursed is he who sleeps with his sister,…
Gen 20:12 Besides, she really is my sister, the daughter of my father—…

whether she was born in the same home or elsewhere.

Different mothers, households, or inheritance arrangements do not alter the reality of the family bond. God’s law leaves no private exception for relationships concealed by distance or complicated family structures. Israel’s distinctness among the nations required sexual conduct shaped by God’s holiness rather than surrounding customs, and believers remain called to honor God with their bodies and flee sexual immorality (1 Corinthians 6:18–20).

Gen 29:16-30 Now Laban had two daughters; the older was named Leah…
2Sa 13:20-22 Her brother Absalom said to her, “Has your brother Amnon…
1Co 5:1 It is actually reported that there is sexual immorality…

You must not have sexual relations with your son’s daughter or your daughter’s daughter,

Grandchildren belong within the protected circle of the household, not as objects of sexual desire or exploitation. God established marriage as the exclusive covenant for sexual union, joining a man and a woman in a new family bond (Genesis 2:24). Incest corrupts that order, violates trust, and brings lasting harm to those whom older family members are responsible to protect.

Deu 27:22 Cursed is he who sleeps with his sister,…
1Co 5:1 It is actually reported that there is sexual immorality…
Gen 19:31-38 One day the older daughter said to the younger,…

for that would shame your family.

Such sin dishonors both the offender and the whole household by destroying family integrity and public witness. Israel was called to live differently from the nations whose sexual practices defiled worship, homes, and communities. God’s people are likewise called to pursue holiness that guards the vulnerable, preserves faithful family bonds, and reflects the purity of the Lord.

2Sa 13:12-13 “No, my brother!” she cried. “Do not violate me”…
Gen 9:22-23 And Ham, the father of Canaan,…
Pro 6:32-33 He who commits adultery lacks judgment;…

You must not have sexual relations with the daughter of your father’s wife,

God forbids sexual union with a daughter born within the household of a father’s marriage. A paternal half-sister was not outside the protected boundaries of the family merely because she had a different mother. Israel was to reject the incestuous practices tolerated among surrounding peoples and honor the order God established for the household.

Deu 27:20 Cursed is he who sleeps with his father’s wife……
Deu 22:30 A man is not to marry his father’s wife…
1Co 5:1 It is actually reported that there is sexual immorality…

born to your father;

Shared descent from the father established a true sibling bond and carried corresponding duties of protection, honor, and restraint. The command guarded the integrity of the family line, inheritance, and household peace, all of which were essential to Israel’s covenant life.

Deu 27:22 Cursed is he who sleeps with his sister,…
Ezk 22:11 One man commits an abomination with his neighbor’s wife;…

she is your sister.

God’s declaration settles the matter: she must be regarded and treated as a sister. Sexual desire must submit to God’s moral boundaries, even within relationships where opportunity or cultural custom might invite compromise. Such holiness anticipates the purity required of God’s people, who belong to Christ and are called to honor Him in their bodies.

Gen 20:12 Besides, she really is my sister, the daughter of my father—…
2Sa 13:11-14 And when she had brought them to him to eat, he took hold…

You must not have sexual relations with your father’s sister;

God forbids sexual union with a paternal aunt, preserving the ordered boundaries He established within the household. Israel was called to reject the practices of surrounding nations and to reflect God’s holiness in private as well as public life. Such boundaries guarded families from betrayal, rivalry, and the disorder caused when God-given relationships were violated.

Lev 20:19 You must not have sexual relations with the sister…
Deu 27:20 Cursed is he who sleeps with his father’s wife……
1Co 5:1 It is actually reported that there is sexual immorality…

she is your father’s close relative.

A father’s sister belongs to the same immediate family line and deserves the honor due to that relationship. Respect for parents includes respect for the family bonds connected to them. God’s commands concerning sexual purity protect the dignity of each person and uphold the household as a place of covenant faithfulness, security, and moral instruction.

Exo 6:20 And Amram married his father’s sister Jochebed,…
Lev 25:49 either his uncle or cousin or any close relative…
Rut 2:20 Then Naomi said to her daughter-in-law, “May he be blessed…

You must not have sexual relations with your mother’s sister,

God forbids sexual union with a maternal aunt, preserving the boundaries He established within the household. Israel was not to imitate the sexual practices of Egypt or Canaan, where God’s order for marriage and family was disregarded. Holiness included honoring the relationships through which God gave life, nurture, and covenant identity.

Lev 20:19 You must not have sexual relations with the sister…
Lev 20:20 If a man lies with his uncle’s wife, he has uncovered…
1Co 5:1 It is actually reported that there is sexual immorality…

for she is your mother’s close relative.

A mother’s sister belongs to the intimate circle of family life and must be treated with honor rather than sexual desire. Such boundaries guarded households from betrayal, rivalry, and confusion, strengthening the community built upon faithful marriages and protected kinship. The command also directs God’s people toward the purity fulfilled in Christ, whose redeemed people are called to honor God with their bodies and to love one another with sincere familial devotion.

Exo 6:20 And Amram married his father’s sister Jochebed,…
Gen 20:12 Besides, she really is my sister, the daughter of my father—…
2Sa 13:12 “No, my brother!” she cried. “Do not violate me”…

You must not dishonor your father’s brother

Israel was commanded to uphold the integrity of the household, including the honor due to extended family. A man’s father’s brother shared in the family’s name, inheritance, and covenant responsibilities. Violating that relationship brought shame upon the family and rejected God’s ordering of kinship. The command stands within the wider biblical call to honor father and mother and to preserve peace, faithfulness, and purity among God’s people.

Lev 20:20 If a man lies with his uncle’s wife, he has uncovered…
1Co 5:1 It is actually reported that there is sexual immorality…

by approaching his wife

Sexual union establishes a bond reserved for marriage. A father’s brother’s wife belonged to the protected circle of close relatives, and approaching her sexually would violate both the uncle and the marriage covenant. Such conduct would introduce betrayal and disorder into a household meant to display covenant faithfulness.

Deu 22:22 If a man is found lying with another man’s wife,…
2Sa 11:4 Then David sent messengers to get her, and when she came…

to have sexual relations with her;

The prohibition addresses deliberate sexual conduct, not merely outward respect. God’s holiness reaches into private actions and desires, requiring His people to reject practices common among the nations around them. Leviticus 20:20 identifies this sin as a serious offense against God’s design for family life.

1Co 6:18 Flee from sexual immorality. Every other sin…
Heb 13:4 Marriage should be honored by all and the marriage bed…

she is your aunt.

Her position as aunt establishes a permanent family boundary. Even where circumstances such as widowhood or divorce might alter a household’s situation, the kinship relationship remained significant; the later provision of levirate marriage applied only to a deceased brother’s widow and did not authorize unions prohibited by God. The command protects the family structure through which God preserved His covenant people.

Lev 20:19 You must not have sexual relations with the sister…
Exo 6:20 And Amram married his father’s sister Jochebed,…

You must not have sexual relations with your daughter-in-law.

God forbids a father from violating the covenant bond between his son and his son’s wife. Such conduct corrupts both generations of a household, betrays the son, and desecrates marriage. Israel was called to reflect God’s holiness in the most private areas of life rather than adopting the immoral practices of surrounding nations.

Lev 20:12 If a man lies with his daughter-in-law…
Ezk 22:11 One man commits an abomination with his neighbor’s wife;…
Gen 38:15-18 When Judah saw her, he thought she was a prostitute…

She is your son’s wife;

Her marriage to the son establishes a family boundary that must be honored. A wife becomes joined to her husband in a covenantal union, and her father-in-law must protect rather than exploit that relationship. The command upholds fidelity, family trust, and the dignity God gives to marriage.

Gen 38:24-26 About three months later, Judah was told…
Gen 38:13-14 When Tamar was told, “Your father-in-law is going up…”…
Gen 38:11 Then Judah said to his daughter-in-law Tamar,…

you are not to have sexual relations with her.

The direct prohibition leaves no place for secrecy, consent, or personal desire to excuse sexual sin. God’s people are to honor marriage as holy and to flee sexual immorality, remembering that their bodies belong to the Lord.

1Co 5:1 It is actually reported that there is sexual immorality…
Deu 27:23 Cursed is he who sleeps with his mother-in-law.…
2Sa 16:22 So they pitched a tent for Absalom on the roof,…

You must not have sexual relations with your brother’s wife;

Marriage joins husband and wife in an exclusive covenant, and a brother’s wife belongs within that protected union. Sexual involvement would violate both the marriage bond and the ordered relationships God established within the household. Deuteronomy 25:5–10 provides a specific exception when a man died without a son: the surviving brother could marry the widow through levirate marriage to preserve the dead brother’s family line. Apart from that divinely regulated provision, such a union was forbidden.

Lev 20:21 If a man marries his brother’s wife, it is an act…
Mrk 6:18 For John had been telling Herod, “It is not lawful for you…”…
Mat 14:4 because John had been telling him, “It is not lawful…

that would shame your brother.

Taking a brother’s wife would expose and dishonor him by treating his marriage as unprotected and his household as open to violation. Leviticus 20:21 attaches the penalty of childlessness to this sin, underscoring its seriousness before God. The command calls God’s people to honor covenant faithfulness, guard family relationships, and reject sexual sin that brings injury and disgrace upon others.

Deu 25:5-10 When brothers dwell together and one of them dies…
Gen 38:8-10 Then Judah said to Onan, “Sleep with your brother’s wife.…
Rut 4:5-10 Then Boaz said, “On the day you buy the land……

You must not have sexual relations with both a woman and her daughter.

Marriage or sexual union with a woman could not be extended to her daughter as though women within one household were possessions available to the same man. Israel was to reject the sexual practices associated with Egypt and Canaan and to preserve the God-given boundaries of the family. Such unions corrupted marriage, violated trust within the household, and brought shame upon those whom a man was responsible to protect.

Lev 20:14 If a man marries both a woman and her mother,…
Ezk 22:10-11 In you they have uncovered the nakedness of their fathers;…
1Co 5:1 It is actually reported that there is sexual immorality…

You are not to marry her son’s daughter or her daughter’s daughter and have sexual relations with her.

The prohibition reaches every generation of a woman’s direct descendants, leaving no opening for exploitation through marriage or sexual access. Daughters and granddaughters were to be treated with honor and protection, not drawn into relationships that confused the proper order of family life. God’s design for marriage in Genesis 2:24 establishes a new household through a husband and wife, while preserving the distinct bonds and responsibilities of the families from which they came.

Lev 20:12 If a man lies with his daughter-in-law…
Lev 20:17 If a man marries his sister, whether the daughter of his…
Deu 27:22 Cursed is he who sleeps with his sister,…

They are close relatives; it is depraved.

Such conduct joined relationships that God had separated and damaged the integrity of the family. Leviticus places these sins among the defiling practices for which the Canaanite peoples faced judgment, warning Israel that sexual sin has consequences beyond private desire. God’s call to holiness required His people to reflect His purity in their homes and bodies. The New Testament continues that standard, condemning incestuous immorality and calling believers to honor God with their bodies.

Deu 27:23 Cursed is he who sleeps with his mother-in-law.…
2Sa 13:12-13 “No, my brother!” she cried. “Do not violate me”…
Gen 19:36 Thus both of Lot’s daughters became pregnant…

You must not take your wife’s sister as a rival wife

Jacob’s marriages to Leah and Rachel brought painful rivalry into one household, with jealousy, competition for children, and conflict between two sisters (Genesis 29–30). God forbids Israel from repeating such an arrangement. Marriage was established as a one-flesh covenant between a man and a woman (Genesis 2:24), and no sister should be brought into a position that wounds her sister or divides the household.

Gen 29:21-30 Finally Jacob said to Laban, “Grant me my wife…
Gen 30:1-8 When Rachel saw that she was not bearing any children…
1Sa 1:6-7 Because the LORD had closed Hannah’s womb……

and have sexual relations with her

Sexual union joins a man and woman in the covenant intimacy of marriage. The command belongs among God’s laws governing sexual holiness, calling Israel to live differently from the nations around them. Fidelity in marriage honors God’s design and guards the family from the sin and disorder that follow sexual unfaithfulness (Exodus 20:14).

Lev 20:17 If a man marries his sister, whether the daughter of his…
Deu 27:22 Cursed is he who sleeps with his sister,…

while your wife is still alive.

The prohibition specifically governs the wife’s lifetime, when taking her sister would make the two women rival wives. Death ends the marriage bond (Romans 7:2–3), but while the covenant remains, the husband must preserve the dignity, faithfulness, and peace of his marriage. The New Testament upholds marriage as a lifelong covenant that reflects Christ’s faithful love for His church (Ephesians 5:31–33).

Rom 7:2-3 For instance, a married woman is bound by law…
1Co 7:39 A wife is bound to her husband as long as he lives.…

You must not approach a woman

God forbids the deliberate pursuit of sexual union when it would violate the boundaries He established for Israel’s holiness.

Exo 19:15 “Be prepared for the third day,” he said to the people.…
Gen 20:6 Then God said to Abimelech in the dream,…
1Co 7:1 It is good to abstain from sexual relations.…

to have sexual relations with her

Sexual intimacy is a gift of God, but it belongs within His covenant order and must not be separated from reverence, self-control, and obedience.

1Co 6:15-18 Do you not know that your bodies are members of Christ?……
1Co 7:2-5 But because there is so much sexual immorality…
Heb 13:4 Marriage should be honored by all and the marriage bed…

during her menstrual period.

Leviticus 15 identifies menstrual flow as a temporary ritual uncleanness, associated with the loss of blood, which represented life before God. Leviticus 20:18 attaches serious consequences to disregarding this command. The law guarded Israel’s worshiping community from treating holy distinctions casually. Christ fulfills the ceremonial requirements of the Law, yet God’s people remain called to honor Him in bodily conduct and sexual purity (1 Peter 1:15–16).

Ezk 18:6 He does not eat at the mountain or look to the idols…
Lev 20:18 If a man lies with a menstruating woman…
Lev 15:19-24 When a woman has a discharge consisting of blood…

You must not lie carnally with your neighbor’s wife

Marriage joins a man and woman in a God-established covenant of exclusive faithfulness (Genesis 2:24). Adultery betrays the husband or wife wronged, violates the marriage bond, and damages the trust and stability of the wider community. Israel’s law treated adultery as a grave sin, punishable by death under the covenant administration of the nation (Leviticus 20:10). The prohibition stands with the seventh commandment and anticipates Christ’s teaching that lustful intent also reveals an unfaithful heart (Exodus 20:14; Matthew 5:27–28).

Pro 6:29 So is he who sleeps with another man’s wife;…
Exo 20:14 You shall not commit adultery.
Deu 5:18 You shall not commit adultery.

and thus defile yourself with her.

Sexual sin brings moral defilement because it misuses bodies created for God’s purposes and corrupts what He has made holy. Such impurity is not merely private; it disrupts fellowship with God and harms others bound to the offender by covenant and community. Jesus taught that defilement proceeds from the heart, where evil desires begin (Mark 7:20–23). Believers are therefore called to flee sexual immorality, honor God with their bodies, and preserve the faithfulness that reflects His covenant love (1 Corinthians 6:18–20).

You must not give any of your children to be sacrificed to Molech,

God forbade Israel from participating in the child sacrifice practiced among surrounding peoples, including the Ammonites. Such offerings treated children, who belonged to God and bore His image, as objects for securing favor from a false god. Later generations of Israel committed this evil in the Valley of Hinnom near Jerusalem, provoking divine judgment (2 Kings 23:10; Jeremiah 32:35). God’s covenant people were to protect life and refuse every form of idolatry, regardless of cultural pressure or promised advantage.

2Ki 23:10 He also desecrated Topheth in the Valley of Ben-hinnom…
Jer 7:31 They have built the high places of Topheth…
Deu 12:31 You must not worship the LORD your God in this way,…

for you must not profane the name of your God.

Child sacrifice would publicly associate the holy God of Israel with the cruelty of pagan worship. Israel bore the Lord’s name as His covenant people, and their conduct was to display His righteous character before the nations. Holiness required more than rejecting false beliefs; it demanded obedience that honored God in family life, worship, and public conduct.

Lev 22:32 You must not profane My holy name. I must be acknowledged…
Ezk 36:20-23 And wherever they went among the nations,…
Ezk 39:7 I will make My holy name known among My people Israel…

I am the LORD.

The command rests on the authority of YHWH, Israel’s covenant God and the only true God. He had redeemed Israel from Egypt and claimed them as His own. Their obedience was to arise from knowing that the Lord is holy, faithful, and sovereign over every nation and every human life.

Exo 20:2 I am the LORD your God, who brought you out…
Exo 6:7 I will take you as My own people, and I will be your God.…
Isa 45:5 I am the LORD, and there is no other; there is no God but Me…

You must not lie with a man as with a woman;

Israel was called to reject the sexual practices of Egypt and Canaan and to live according to the order established by the Creator. God made humanity male and female and ordained marriage as the covenant union of one man and one woman. The prohibition addresses male same-sex intercourse as contrary to that design. The New Testament maintains this moral teaching while also proclaiming cleansing and new life through Christ for all who repent and believe (Romans 1:26–27; 1 Corinthians 6:9–11).

Rom 1:26-27 For this reason God gave them over to dishonorable passions.…
1Co 6:9-10 Do not be deceived: Neither the sexually immoral…
1Ti 1:9-10 We realize that law is not enacted for the righteous,…

that is an abomination.

God identifies such conduct as grievously opposed to His holiness, not merely as a violation of Israelite custom. Leviticus 18 links these sins with the defilement of the nations and warns Israel not to follow their ways. God’s judgment against sexual sin reveals His concern for the purity of His people, the honor of marriage, and faithful obedience to His revealed will. His call to holiness is joined to His mercy, for those redeemed by Christ are summoned to leave former sins behind and walk in obedience.

Lev 20:13 If a man lies with a man as with a woman,…
Jud 1:7 In like manner, Sodom and Gomorrah and the cities…
Rev 21:8 But to the cowardly and unbelieving and abominable…

You must not lie carnally with any animal,

God established mankind as distinct from the animals and uniquely bearing His image, entrusted with dominion over creation rather than sexual union with it (Genesis 1:26–28). Sexual intimacy belongs within the covenant of marriage between man and woman and is ordered toward faithful companionship and fruitfulness. Israel was forbidden to imitate the corrupt practices of Egypt and Canaan, where pagan religion often blurred God-given boundaries. Exodus 22:19 and Deuteronomy 27:21 repeat the prohibition, showing that such conduct was incompatible with life among God’s holy people.

Lev 20:15 If a man lies carnally with an animal…
Exo 22:19 Whoever lies with an animal must surely be put to death.
Deu 27:21 Cursed is he who lies with any animal.…

thus defiling yourself with it;

Such sin brought moral defilement because it rebelled against the Creator’s design and profaned the body. Defilement was not merely a private matter; it affected the worshiping community and contradicted Israel’s calling to dwell near a holy God. Jesus later taught that moral evil proceeds from the human heart and truly defiles a person (Mark 7:20–23). Forgiveness requires repentance and the cleansing God provides through atonement.

Psa 106:39 They defiled themselves by their actions…
Rom 1:24 Therefore God gave them over to impurity…
1Co 6:18 Flee from sexual immorality. Every other sin…

a woman must not stand before an animal to mate with it;

The command explicitly includes women, making clear that no person was exempt from God’s moral order. Human sexuality was not to be surrendered to animal instinct, exploited in idolatrous ritual, or separated from the covenant purposes established in creation. God’s people were to honor the dignity of the human body and preserve the distinctions He made.

Lev 20:16 If a woman approaches any animal to mate with it,…
Rom 1:26-27 For this reason God gave them over to dishonorable passions.…

that is a perversion.

The act is condemned as a gross distortion of what God called good in creation. It overturns the proper relationship between humanity and the animal world and treats a sacred gift as an instrument of rebellion. The severity of the prohibition emphasizes that holiness includes honoring God not only in public worship but also in the most private uses of the body.

Jud 1:7 In like manner, Sodom and Gomorrah and the cities…
2Pe 2:10 Such punishment is specially reserved for those who indulge…
1Ti 1:10 for the sexually immoral, for homosexuals, for slave traders…

Do not defile yourselves by any of these practices,

God forbade Israel to participate in the sexual immorality, child sacrifice, and idolatrous worship described in Leviticus 18. Holiness required more than separation from ceremonial uncleanness; it required moral faithfulness to the Lord. Israel belonged to God by covenant and was not free to adopt the customs of the land.

Deu 18:9-12 When you enter the land that the LORD your God gives you,…
Lev 20:7 Consecrate yourselves, therefore, and be holy,…
Ezk 20:7 And I said to them: ‘Each of you must throw away…

for by all these things the nations

The Canaanite peoples had persistently practiced the sins God prohibited, including acts that corrupted marriage, family, worship, and human life. Their conduct revealed rebellion against the Creator’s order and brought guilt upon the land they inhabited.

Deu 9:4-5 When the LORD your God has driven them out before you,…
Deu 12:30-31 be careful not to be ensnared by their ways…
Gen 15:16 In the fourth generation your descendants will return here……

I am driving out before you

The coming conquest of Canaan was God’s judgment on entrenched wickedness and the fulfillment of His promise to give Abraham’s descendants the land. Israel would enter by God’s power, not by its own strength, and was therefore accountable to obey the God who gave the victory.

Exo 23:28-31 I will send the hornet before you to drive the Hivites…
Deu 7:1-2 When the LORD your God brings you into the land…
Jos 23:5 The LORD your God will push them out of your way…

have defiled themselves.

The nations had made themselves morally and spiritually unclean through continual sin. Their removal warned Israel that covenant privilege would not excuse the same rebellion. God’s people were called to live distinctly before Him, anticipating the cleansing from sin ultimately provided through Christ.

Psa 106:38-39 They shed innocent blood—the blood of their sons…
Ezk 36:17-18 Son of man, when the people of Israel lived in their land,…
Isa 24:5 The earth is defiled by its people; they have overstepped…

Even the land has become defiled,

God gave Canaan as an inheritance, yet its inhabitants had filled it with idolatry, sexual immorality, child sacrifice, and other abominations. Human rebellion brought defilement upon the place where God had set His name and purposes. Bloodshed and idolatry pollute the land before the holy God, who is Lord of all creation.

Num 35:33 Do not pollute the land where you live, …
Psa 106:38 They shed innocent blood—the blood of their sons…
Ezk 36:17 Son of man, when the people of Israel lived in their land,…

so I am punishing it for its sin,

God’s judgment upon the land came through His judgment upon the people who had corrupted it. The Canaanites were not displaced merely because Israel desired their territory; their removal followed centuries of persistent evil and fulfilled God’s righteous sentence (Genesis 15:16; Deuteronomy 9:4–5). Israel’s possession of the land therefore rested on covenant faithfulness, not ethnic privilege.

Hos 8:13 Though they offer sacrifices as gifts to Me…
Jer 2:19 Your own evil will discipline you; your own apostasies…
Ezk 7:8-9 Very soon I will pour out My wrath upon you…

and the land will vomit out its inhabitants.

The severe image portrays expulsion from the land as the consequence of enduring impurity. Israel was warned that the same judgment would fall on them if they adopted Canaanite practices (Leviticus 18:28; 20:22). Later exile from the land demonstrated that God judges His own people without partiality. The removal of the wicked anticipates the final judgment in which all evil will be excluded from God’s holy kingdom.

Lev 20:22 You are therefore to keep all My statutes and ordinances,…
2Ch 7:20 then I will uproot Israel from the soil I have given them…
Deu 28:63-64 Just as it pleased the LORD to make you prosper…

But you are to keep My statutes and ordinances,

The Lord’s commands governed Israel’s worship, moral conduct, family life, and public justice under the covenant given through Moses. Obedience marked Israel as God’s holy people and guarded the fellowship He had established with them (Exodus 19:5–6; Deuteronomy 6:1–3).

Deu 11:1 You shall therefore love the LORD your God…
Deu 6:1 These are the commandments and statutes and ordinances…
Jos 1:7 Above all, be strong and very courageous.…

and you must not commit any of these abominations—

The forbidden sexual practices listed in Leviticus 18 violated God’s design for marriage, family, and human sexuality. Canaanite nations had defiled the land through such sins and were coming under divine judgment (Leviticus 18:24–25). Israel was not to imitate the corruption around them but to live in holiness before the Lord.

Deu 12:31 You must not worship the LORD your God in this way,…
Deu 18:9 When you enter the land that the LORD your God gives you,…

neither your native-born nor the foreigner who lives among you.

Every person dwelling within Israel’s covenant community was accountable to God’s moral order. Foreign residents received protection and justice, yet they were not free to bring the practices of other nations into the land. One standard upheld the holiness of the community and pointed beyond Israel to God’s righteous rule over all peoples.

Exo 12:49 The same law shall apply to both the native…
Num 15:15-16 The assembly is to have the same statute both for you…
Lev 24:22 You are to have the same standard of law…

For the men who were in the land before you

The Canaanites occupied the land God promised to Abraham’s descendants. Their long-standing rebellion had reached the measure of judgment, and God removed them from the land while bringing Israel in (Genesis 15:16; Deuteronomy 9:4–5). Israel was not to adopt the customs of the people they displaced.

Deu 12:29-31 When the LORD your God cuts off before you the nations…
Deu 9:4-5 When the LORD your God has driven them out before you,…
Gen 15:16 In the fourth generation your descendants will return here……

committed all these abominations,

Canaanite religion joined idolatry with sexual immorality, child sacrifice, divination, and other practices forbidden by God. The commands of Leviticus 18 reveal that such sins were not private matters but open patterns of life that rejected God’s created order and corrupted worship.

Deu 18:9-12 When you enter the land that the LORD your God gives you,…
2Ki 21:11 Since Manasseh king of Judah has committed…
Jer 32:35 They have built the high places of Baal in the Valley…

and the land has become defiled.

The land belonged ultimately to the Lord, and human sin brought pollution upon the place where He chose to dwell among His people. Canaan’s defilement explains the severity of its judgment and warns Israel that covenant privilege would not excuse similar rebellion. If Israel embraced the same abominations, the land would also cast them out.

Num 35:33-34 Do not pollute the land where you live, …
Ezk 36:17-18 Son of man, when the people of Israel lived in their land,…
Jer 3:1-2 If a man divorces his wife and she leaves him…

So if you defile the land,

Canaan belonged to the Lord, who gave it to Israel as the place where His covenant people were to live under His rule. Sin was not private or harmless; idolatry, sexual immorality, bloodshed, and rebellion against God corrupted the life of the whole nation. Israel’s calling to holiness included faithful worship, just conduct, and moral purity within the land God had entrusted to them.

Num 35:33-34 Do not pollute the land where you live, …
Jer 2:7 I brought you into a fertile land to eat its fruit…
Ezk 36:17 Son of man, when the people of Israel lived in their land,…

it will vomit you out

The land is pictured as rejecting inhabitants whose sins had become intolerable before God. Israel could not presume upon God’s promise to Abraham while despising God’s commands. The warning was fulfilled in the exile, when persistent idolatry and injustice brought the judgments announced through the prophets, and Judah was carried into Babylon.

Lev 20:22 You are therefore to keep all My statutes and ordinances,…
Deu 28:63-64 Just as it pleased the LORD to make you prosper…
Deu 4:26-27 I call heaven and earth as witnesses against you this day…

as it spewed out the nations before you.

The Canaanite peoples had filled the land with practices God called abominations, and their judgment had reached its appointed time (Genesis 15:16). Israel received the land by God’s grace, not because of superior righteousness (Deuteronomy 9:4–6). The same holy God who judged the nations would judge Israel if they embraced the sins for which those nations were removed.

Deu 11:23 then the LORD will drive out all these nations before you…
Deu 7:1-2 When the LORD your God brings you into the land…
Deu 9:4-5 When the LORD your God has driven them out before you,…

Therefore anyone who commits any of these abominations

God holds every member of Israel accountable for the sexual sins forbidden in Leviticus 18. The Canaanite nations had filled the land with such defilement, and God was driving them out under His judgment. Israel was not to imitate the surrounding peoples, for covenant privilege required covenant obedience. Sexual sin violated God’s design for marriage, family, worship, and the holiness of the community.

Lev 20:13 If a man lies with a man as with a woman,…
Deu 27:20-23 Cursed is he who sleeps with his father’s wife……
Lev 20:17 If a man marries his sister, whether the daughter of his…

must be cut off from among his people.

Removal from Israel declared that persistent rebellion against God could not be treated as a private matter. Depending on the offense, being cut off involved death, judicial punishment, or God’s direct judgment, as later laws in Leviticus 20 clarify. The penalty guarded the covenant community from corruption and testified that God is holy. Christ bore judgment for sin so that repentant sinners may be forgiven and restored, yet His grace never overturns God’s call to holiness.

Gen 17:14 But if any male is not circumcised, he will be…
Exo 12:15 For seven days you must eat unleavened bread.…
Num 15:30-31 But the person who sins defiantly, whether a native…

You must keep My charge

Israel was bound to guard God’s commands as the people redeemed from Egypt and called to belong to Him. Obedience preserved the covenant order God established among His people.

1Ki 2:3 And keep the charge of the LORD your God to walk in His ways…
Gen 26:5 because Abraham listened to My voice and kept My charge…
Deu 11:1 You shall therefore love the LORD your God…

not to practice any of the abominable customs

The forbidden practices included the sexual immorality, incest, adultery, child sacrifice, and idolatrous corruption condemned throughout Leviticus 18. God’s people were not to adopt the worship or morals of nations that rejected Him.

Deu 18:9 When you enter the land that the LORD your God gives you,…
Deu 20:18 so that they cannot teach you…
Deu 12:31 You must not worship the LORD your God in this way,…

that were practiced before you,

The Canaanite peoples had filled the land with such sins, and God’s judgment against them was connected to their persistent corruption. Israel entered the land as a holy people, not as heirs of its former religious and moral patterns.

Deu 9:4-5 When the LORD your God has driven them out before you,…
Exo 23:31 And I will establish your borders from the Red Sea……
Deu 31:3 The LORD your God Himself will cross over ahead of you.…

so that you do not defile yourselves by them.

Sin brought moral and spiritual defilement, making people unfit for fellowship with the holy God who dwelt among them. The same practices that had defiled the land would bring judgment upon Israel if they embraced them.

Ezk 20:7 And I said to them: ‘Each of you must throw away…
Ezk 20:31 When you offer your gifts, sacrificing your sons in the fire…
Psa 106:39 They defiled themselves by their actions…

I am the LORD your God.”

The Lord’s covenant authority was the foundation for Israel’s obedience. He had chosen, redeemed, and claimed them as His own; therefore, their lives were to reflect His holiness rather than the ways of the nations.

Exo 20:2 I am the LORD your God, who brought you out…
Lev 11:44 For I am the LORD your God; consecrate yourselves…
Ezk 20:5 This is what the Lord GOD says: On the day I chose Israel…
