Leviticus 18:17 violation effects?
What are the consequences of violating the prohibitions in Leviticus 18:17?

The Plain Text of the Command

• “You must not have sexual relations with both a woman and her daughter. You are not to take her son’s daughter or her daughter’s daughter to have sexual relations with them. They are close relatives; this is wickedness.” (Leviticus 18:17)


What Violating It Meant in Ancient Israel

• The act was labeled “wickedness,” a term reserved for the most flagrant moral offenses.

• It shattered God-ordained family boundaries, corrupting the relational fabric He established (cf. Genesis 2:24).

• It desecrated the covenant community’s holiness, which God required for His people to remain in His presence (Leviticus 19:2).


Stated Penalties in the Law

• Capital judgment: “If a man marries a woman and her mother, it is depravity; both he and they are to be burned with fire, so that there will be no depravity among you” (Leviticus 20:14).

• The death penalty purged the evil and served as a deterrent (Deuteronomy 13:5; 17:12).

• The offender’s name and legacy were cut off from Israel—no inheritance, no standing, no place among God’s people (Numbers 15:30–31).


Spiritual and Relational Fallout

• Personal defilement: Sin severs fellowship with a holy God (Isaiah 59:2).

• Family devastation: Trust, honor, and protection within the household collapse.

• Community contamination: “You shall remove the evil from among you” (Deuteronomy 22:24) underscores corporate responsibility to confront sin.


Far-Reaching National Consequences

• Land defilement: “Do not defile yourselves… so the land does not vomit you out” (Leviticus 18:24-25).

• Exile threat: Persisting in such sins led to eventual displacement from the Promised Land (2 Kings 17:7-18).

• Loss of blessing: God withheld prosperity and protection when Israel tolerated moral corruption (Deuteronomy 28:15-68).


New Testament Echoes

• Sexual immorality—including incest—bars the unrepentant from God’s kingdom (1 Corinthians 6:9-10).

• Paul demands church discipline for incest to “deliver such a one to Satan for the destruction of the flesh” (1 Corinthians 5:1-5).

• God still calls His people to holiness: “Marriage should be honored by all, and the marriage bed kept undefiled” (Hebrews 13:4).


Takeaways for Today

• God’s design for sexuality is protective, not restrictive; violating it invites judgment and heartache.

• Sin affects more than the individual—it wounds families, churches, and cultures.

• Christ’s atonement offers forgiveness, yet genuine repentance and separation from sin remain non-negotiable (1 John 1:9).
