Bible Verses About Adultery
Introduction
Adultery is one of the subjects the Bible addresses with both complete clarity and surprising depth. The clarity is in the prohibition: adultery is named in the Ten Commandments, condemned by the prophets, and addressed directly by Jesus. The depth is in how Scripture treats it, not merely as a legal violation but as a window into something much larger about covenant, faithfulness, desire, and the character of God himself.
The most striking thing about the biblical treatment of adultery is the way God uses it as a metaphor for Israel's unfaithfulness to him. The prophets Hosea, Jeremiah, and Ezekiel all describe Israel's idolatry as adultery against God, which means the prohibition is not merely a social rule for stable families. It is grounded in the nature of covenant itself, in the exclusive and faithful love that defines the relationship between God and his people, and by extension between husband and wife.
These verses speak to anyone who has committed adultery and is carrying the weight of it, anyone whose marriage has been damaged by it, anyone trying to understand what Jesus means when he extends the prohibition into the realm of the heart, and anyone seeking to understand the biblical vision of covenant faithfulness that adultery violates.
What the Bible Means When It Talks About Adultery
The Hebrew word na'aph and the Greek word moicheia both refer specifically to sexual relations between a married person and someone who is not their spouse. In the ancient world the legal definitions varied, but the biblical prohibition is consistent and applies to both men and women, though its application in the culture of the ancient Near East was not always symmetrical in practice.
What distinguishes the biblical treatment from purely legal approaches is the grounding of the prohibition in covenant. Marriage in Scripture is not merely a social contract. It is a covenant witnessed by God (Malachi 2:14), sealed by vows, and intended to reflect the covenant love between God and his people. Adultery is therefore not only a violation of a promise to a spouse. It is a violation of the covenant structure that God designed marriage to embody.
Bible Verses About the Prohibition of Adultery
Exodus 20:14 — ("You shall not commit adultery.") The seventh commandment is stated without qualification or exception. Its brevity is its force. The prohibition stands as one of the ten foundational words that define covenant life with God and with one another.
Leviticus 20:10 — ("If a man commits adultery with another man's wife — with the wife of his neighbor — both the adulterer and the adulteress are to be put to death.") The severity of the Old Testament penalty reflects the seriousness with which the covenant violation was treated. Both parties are named, which is notable in a culture that often held only the woman responsible. The bilateral accountability reflects the bilateral nature of the violation.
Proverbs 6:32 — ("But a man who commits adultery has no sense; whoever does so destroys himself.") Proverbs addresses adultery from the perspective of wisdom and its consequences. The one who commits adultery is described as lacking sense because the damage done to oneself is as real as the damage done to others. The destruction is self-directed as well as outward.
Hebrews 13:4 — ("Marriage should be honored by all, and the marriage bed kept pure, for God will judge the adulterer and all the sexually immoral.") The honoring of marriage and the purity of the marriage bed are paired with the warning that God will judge those who violate them. The judgment is God's, which places the accountability for adultery within the vertical relationship with God rather than only within the horizontal relationship between people.
Malachi 2:14 — ("You ask, 'Why?' It is because the LORD is the witness between you and the wife of your youth. You have been unfaithful to her, though she is your partner, the wife of your marriage covenant.") God's role as witness to the marriage covenant means that unfaithfulness to a spouse is unfaithfulness before God. The covenant is not only between two people. It is made in the presence of and before the one who witnesses all covenants.
Bible Verses About Adultery of the Heart
Matthew 5:27-28 — ("You have heard that it was said, 'You do not commit adultery.' But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.") Jesus extends the prohibition from the act to the intention behind it. The lustful look that treats another person as an object of desire rather than as a person created in God's image is already a violation of the spirit of the commandment. The heart is the location of the commandment's deepest application.
Matthew 5:29-30 — ("If your right eye causes you to stumble, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell. And if your right hand causes you to stumble, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to go into hell.") The hyperbolic language of cutting off and gouging out communicates the radical seriousness with which the sources of lustful desire are to be addressed. The exaggeration is intentional. The point is not literal self-mutilation but the willingness to take whatever measures are necessary to address the problem at its root.
Job 31:1 — ("I made a covenant with my eyes not to look lustfully at a young woman.") Job's covenant with his eyes is the practical application of the principle Jesus articulates. The discipline of where the eyes go is the first line of defense against the desire that adultery begins with. Job's covenant is proactive rather than reactive.
Proverbs 4:23 — ("Above all else, guard your heart, for everything you flows from it.") The guarding of the heart is the broader context in which the specific guarding against lustful desire belongs. What is allowed into the heart shapes what flows out of it into behavior. The vigilance required is not primarily behavioral but attentional.
Bible Verses About Adultery and the Covenant of Marriage
Matthew 19:4-6 — ("Haven't you read,' he replied, 'that at the beginning the Creator made them male and female, and said, "For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh"? So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.'") Jesus grounds the prohibition of adultery in the creation intention for marriage. The one flesh unity that marriage creates is what adultery fractures. The what God has joined together is the basis for the let no one separate. The gravity of adultery is proportional to the gravity of what it destroys.
Proverbs 5:15-18 — ("Drink water from your own cistern, running water from your own well. Should your springs overflow in the streets, your streams of water in the public squares? Let them be yours alone, never to be shared with strangers. May your fountain be blessed, and may you rejoice in the wife of your youth.") Proverbs 5 uses the extended metaphor of water and cisterns to describe sexual faithfulness within marriage. The exclusivity of the marriage relationship, the keeping of what is precious within its proper boundaries, is the counsel of wisdom against the pull toward adultery.
1 Corinthians 7:3-5 — ("The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. The wife does not have authority over her own body but yields it to her husband. In the same way, the husband does not have authority over his own body but yields it to his wife. Do not deprive each other except perhaps by mutual consent and for a time, so that you may devote yourselves to prayer. Then come together again so that Satan will not tempt you because of your lack of self-control.") Paul's counsel about the sexual relationship within marriage is practical and honest about the role that mutual fulfillment plays in protecting the marriage from the temptation that neglect creates. The coming together again is presented as a safeguard against the vulnerability that deprivation produces.
Bible Verses About God's Faithfulness Contrasted With Adultery
Hosea 2:19-20 — ("I will betroth you to me forever; I will betroth you in righteousness and justice, in love and compassion. I will betroth you in faithfulness, and you will acknowledge the LORD.") The book of Hosea uses the marriage metaphor throughout to describe God's faithfulness to an unfaithful Israel. The divine betrothal in righteousness, justice, love, compassion, and faithfulness is the model of the covenant love that human marriage is meant to reflect. God's response to Israel's adultery is not abandonment but renewed pursuit.
Jeremiah 3:20 — ("But like a woman unfaithful to her husband, so you, Israel, have been unfaithful to me, declares the LORD.") The accusation of unfaithfulness toward God is framed precisely as adultery. The metaphor works because marriage and covenant with God share the same structure: exclusive, faithful, covenantal love. To violate either is to violate the same principle.
Ezekiel 16:8 — ("Later I passed by, and when I looked at you and saw that you were old enough for love, I spread the corner of my garment over you and covered your nakedness. I gave you my solemn oath and entered into a covenant with you, declares the Sovereign LORD, and you became mine.") The covenant that God made with Israel is described in the language of marriage, with the spreading of the garment as a pledge of protection and faithfulness. The context is Ezekiel's extended metaphor of Israel's adultery against this covenant love. The depth of the betrayal is proportional to the depth of what was pledged.
Bible Verses About Forgiveness and Restoration After Adultery
John 8:10-11 — ("Jesus straightened up and asked her, 'Woman, where are they? Has no one condemned you?' 'No one, sir,' she said. 'Then neither do I condemn you,' Jesus declared. 'Go now and leave your life of sin.'") The encounter with the woman caught in adultery is the most direct gospel treatment of adultery's aftermath. Jesus does not minimize the sin. He dismisses the condemnation and issues the call to leave the life of sin. The neither do I condemn you and the go and sin no more belong together. The forgiveness is real and the call to change is real.
Psalm 51:1-2 — ("Have mercy on me, O God, according to your unfailing love; according to your great compassion blot out my transgressions. Wash away all my iniquity and cleanse me from my sin.") Psalm 51 is David's prayer of repentance after his adultery with Bathsheba. The appeal is to God's unfailing love and great compassion rather than to his own worthiness. The blotting out, washing, and cleansing describe the thoroughness of the forgiveness he seeks.
Psalm 51:10 — ("Create in me a pure heart, O God, and renew a steadfast spirit within me.") The prayer for a pure heart acknowledges that the problem of adultery goes deeper than behavior to the heart from which behavior flows. The creation of a pure heart is God's work rather than the person's achievement. The steadfast spirit is the stability of character that faithfulness requires.
1 John 1:9 — ("If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.") The purification from all unrighteousness includes the unrighteousness of adultery. The faithfulness and justice of God are the grounds of the forgiveness. The confession is the condition. The forgiveness is the promise.
Isaiah 43:25 — ("I, even I, am he who blots out your transgressions, for my own sake, and remembers your sins no more.") The blotting out of transgressions and the not-remembering of sins is the promise that makes restoration after adultery possible. The for my own sake is striking: God's forgiveness is motivated by his own character rather than by the merit of the one being forgiven.
A Simple Way to Pray These Verses
Adultery, whether committed or suffered, requires honest prayer. These verses give words to both the confession and the grief.
Psalm 51:1 — ("Have mercy on me, O God, according to your unfailing love.") Response: "I have nothing to bring but the appeal to your mercy. I am making that appeal."
John 8:11 — ("Neither do I condemn you. Go now and leave your life of sin.") Response: "I receive the not condemned. I am choosing to live differently. I need your help to do it."
Malachi 2:14 — ("The LORD is the witness between you and the wife of your youth.") Response: "You saw the covenant made. You see the damage done. I am bringing both to you."
Frequently Asked Questions
What does the Bible say about adultery? The Bible prohibits adultery consistently from the Ten Commandments through the New Testament. It grounds the prohibition in the covenant nature of marriage rather than merely in social convention. Jesus extends the prohibition from the act to the heart, naming lustful desire as the beginning of the violation. The prophets use adultery as a metaphor for Israel's unfaithfulness to God, which reveals how deeply the prohibition is rooted in the nature of covenant love itself. Forgiveness for adultery is available through genuine repentance, as David's Psalm 51 and Jesus' encounter with the woman caught in adultery both demonstrate.
What did Jesus say about adultery? Jesus addressed adultery in two primary contexts. In the Sermon on the Mount (Matthew 5:27-28) he extended the prohibition from the act to the intention, naming lustful looking as adultery of the heart. He also responded to the woman caught in adultery (John 8:1-11) by dismissing the condemnation of her accusers and extending forgiveness while calling her to leave her life of sin. In Matthew 19 he addressed the question of divorce and adultery by grounding both in the creation intention for marriage as a one flesh union that God joins together.
Is adultery unforgivable? No. The consistent testimony of Scripture is that genuine repentance and confession are met with forgiveness. Psalm 51, written by David after his adultery with Bathsheba, is one of the great prayers of repentance in the Bible and is treated by Scripture as a model of genuine contrition met by genuine forgiveness. First John 1:9 promises purification from all unrighteousness to those who confess. The encounter in John 8 shows Jesus extending forgiveness to a woman caught in the act. Adultery is serious and its consequences are real and lasting, but it is not beyond the reach of God's forgiveness.
What is the difference between adultery and lust? Adultery is the physical act of sexual relations with someone who is not one's spouse. Lust, as Jesus describes it in Matthew 5:28, is the intentional, sustained desire for another person that treats them as an object of gratification. Jesus says that this internal act already constitutes adultery of the heart. The distinction matters because it reveals that the prohibition is about the whole person, not only external behavior. It also matters pastorally because many people who have not committed adultery physically carry real guilt about what has happened in the heart.
How do you rebuild a marriage after adultery? Scripture does not provide a step-by-step program but does provide the essential elements. Genuine repentance and honest confession are the beginning. The forgiveness that God extends and the forgiveness that the injured spouse may extend over time are both essential. The rebuilding of trust is a long process that requires consistent faithfulness and the kind of accountability that prevents isolation. Community support, often including pastoral care and professional counseling, is a genuine means of the help God provides. The marriage may or may not survive, but where both parties are willing, the God who restores is the same God who witnessed the covenant.
