Link Deut 22:22 & Ten Commandments adultery?
What connections exist between Deuteronomy 22:22 and the Ten Commandments on adultery?

Setting the Stage: Two Passages, One Standard

Deuteronomy 22:22

“If a man is found lying with a married woman, then both the man who lay with the woman and the woman must die. You must purge the evil from Israel.”

Exodus 20:14

“You shall not commit adultery.”


Shared Divine Origin

• Both texts flow from God’s unchanging character.

• The Ten Commandments give the foundational moral decree; Deuteronomy supplies detailed case law for daily life in Israel.

• Neither passage is optional advice—each carries divine authority and remains morally binding.


Expanding the Command: From Principle to Case Law

Exodus 20:14 states the principle in six Hebrew words.

Deuteronomy 22:22 shows how that principle is enforced when someone actually violates it.

• The case law:

– Identifies the crime (sexual intercourse with another man’s wife).

– Names both participants as guilty; no favoritism.

– Prescribes capital punishment, underscoring the seriousness God places on marital fidelity.

• This movement from headline command to courtroom application mirrors other commandments (e.g., “You shall not murder” → case laws on manslaughter, accidental death).


The Purpose Behind the Penalty

• “Purge the evil from Israel” (Deuteronomy 22:22) shows God’s concern for communal holiness, not just private morality.

• Strong judgment serves as deterrent, protecting families and preserving covenant life.

Hebrews 13:4 echoes the same heart: “Marriage should be honored by all, and the marriage bed kept undefiled…”


Consistency of Moral Law Throughout Scripture

• Jesus reaffirms the seventh commandment and intensifies its reach: “Everyone who looks at a woman to lust after her has already committed adultery with her in his heart” (Matthew 5:28).

• Paul presses the same ethic for believers (1 Corinthians 6:9-10; Hebrews 13:4).

• No text in Scripture relaxes God’s standard; instead, grace empowers obedience (Titus 2:11-12).


Marriage as Covenant: The Core Issue

• Adultery attacks covenant fidelity, a living picture of God’s covenant with His people (Malachi 2:14; Ephesians 5:31-32).

• By enforcing severe penalties, God safeguards a symbol of His own faithfulness.

• Breaking marriage vows therefore carries theological weight far beyond personal betrayal.


Practical Takeaways for Today

• Honor God’s design: one man, one woman, lifelong covenant.

• Guard heart and eyes; adultery begins in desire before it moves to deed (Job 31:1; Matthew 5:27-28).

• Repent quickly if you’ve drifted—grace is available, but God’s standard has not changed (1 John 1:9).

• Champion faithfulness in the church and culture, reflecting God’s unwavering fidelity to His people.
