Exodus 20:14 Meaning: You Shall Not Commit Adultery
Short answer: Exodus 20:14 says, “You shall not commit adultery.” This is the seventh of the Ten Commandments, given at Sinai to a people freshly rescued from Egypt. It forbids sexual intercourse between a married person and someone who is not their spouse, and it treats marriage as a boundary God himself has drawn, not one that couples or cultures may redraw. The command rests on the creation order, where God made one man and one woman and joined them as one flesh. It protects the spouse who would be betrayed, any children involved, and the wider community that depends on families keeping faith. Scripture is honest that this sin is devastating, and it is equally honest that God forgives those who repent and turn to Christ.
The Setting of the Command at Sinai
Before we examine the command itself, we should notice where it stands. Israel had just been brought out of Egypt by a mighty deliverance, and God brought them to Mount Sinai to make a covenant with them. The Ten Commandments are not the terms on which God agreed to rescue them; they are the way of life for a people already rescued. Grace comes first, obedience follows. This order matters enormously for how we read Exodus 20:14. Adultery is forbidden not because God is stingy with human happiness but because he has committed himself to this people and knows what destroys them. The command is a fence around a garden, not a wall around a prison.
The commandments were spoken aloud to the whole assembly and then written on stone. That combination of speech and stone tells us something. God wanted these words heard, remembered, and permanent. They are not tribal customs that expire with a generation. In the middle of the list, the seventh command sits among the shortest of the ten, only a handful of words in Hebrew. Its brevity is striking. There is no long preamble, no case law attached here. The command simply names the act and forbids it. The surrounding case laws in Exodus 21 and 22 will work out details of restitution and justice, but the Decalogue itself gives the unadorned principle.
Placement also matters. The commandments about murder, adultery, and stealing come in sequence. Each one protects something God values: life, marriage, property. To break the seventh is to attack a person’s most intimate bond in a way that a stolen possession cannot match. Some readers of the Old Testament imagine that its sexual ethics were merely about property and heirs, but that reading is too small. The prophets later describe covenant unfaithfulness in marriage as a living picture of what Israel did to God. Hosea’s whole life becomes a sign of it. The command against adultery is therefore rooted in the character of God, who keeps covenant and does not betray those who belong to him.
The setting also tells us that God speaks to a community, not only to individuals. The Ten Commandments were given to a gathered people who would live in close quarters, sharing wells, fields, and futures. Adultery in such a setting was not a private matter between consenting adults. It was a tear in the fabric everyone lived in. The command is addressed to each person, and it is also addressed to a people who must guard one another’s marriages. That communal dimension is easy to lose in modern Western life, where marriage is often imagined as a private contract between two people. Scripture treats it as a covenant with public weight.
What the Word Adultery Means in Scripture
The Hebrew term behind Exodus 20:14 refers specifically to sexual relations between a married person and someone other than their spouse, or between two people where at least one is married to another. It is narrower than the general category of sexual sin. Other passages address other cases, including premarital relations, prostitution, and various forms of unlawful union. So the seventh commandment is a targeted prohibition, and it assumes the institution it protects. Israel already knew what marriage was; God had established it at creation, long before Sinai. The command does not create marriage, it shields it. We should be careful not to flatten every sexual sin into adultery, and careful not to imagine that only adultery matters to God.
Adultery in the ancient world was understood as a wrong against a husband or a wife, and the Old Testament penalties were severe because the offense struck at the heart of family and inheritance. But the underlying offense was against God. David confesses after his sin with Bathsheba that he has sinned against the Lord, and he does not mean that Uriah and Bathsheba did not matter. He means the deepest offense was to the God whose law he broke. That is the pattern throughout Scripture. Every command in the Decalogue has a vertical dimension. Stealing dishonors the God who provides; lying dishonors the God of truth; adultery dishonors the God who joins. The seventh command is violated against a spouse, and it is violated against heaven.
It is worth noticing that the command is given in the second person singular, addressed to each Israelite, and yet it was given to a whole nation. It says, you, not merely whoever happens to be married. This means the unmarried are not exempt from its demands. A single person who pursues someone else’s spouse breaks this command as surely as the married person does. A person who encourages such a relationship participates in it. The command also bears on the community that looks the other way, covers for a friend, or jokes about an affair. The law of God addresses our complicity, not only our direct acts. That is uncomfortable and necessary.
Finally, we must remember that adultery was capital in Israel’s civil code, but the law also provided a path for mercy and restoration in other cases, and the prophets call for forgiveness even as they denounce the sin. The New Testament will not soften the command; it will deepen it. But it will also make plain that adulterers can be washed, sanctified, and justified in the name of the Lord Jesus Christ. Exodus 20:14 stands in a Bible that ends with a wedding supper and a bride made ready, a Bible that treats marriage with enormous seriousness and treats repentant sinners with enormous mercy. Both truths come from the same God.
Why Marriage Is Worth Guarding
Marriage is the first human institution God established, before government, before the temple, before Israel existed. God made a woman from the man’s side and brought her to him, and the man said she was bone of his bones and flesh of his flesh. In Matthew 19:4-6 Jesus quotes that passage and concludes that what God has joined together, man must not separate. Jesus treats the Genesis account as historical and as authoritative. If marriage is a divine joining, then adultery is a tearing of something God himself wove together. The seventh commandment is not an arbitrary rule about bodies; it is a guard around a union God made. The command assumes that marriage is a covenant with a witness, and the witness is God.
Marriage is also the ordinary context in which children are raised and faith is passed on. This is why the seventh commandment sits so close to the command about honoring father and mother. A stable marriage gives children a world they can trust. When adultery fractures a home, the consequences ripple through generations, and often the deepest wounds are not the ones the adults feel but the ones their children carry silently. This is one reason the Old Testament prophets speak so fiercely about covenant breaking. Malachi records God’s rebuke of men who dealt treacherously with the wives of their youth. God says he hates divorce and the violence it brings, and the reason given is that he desires godly offspring. Adultery attacks the soil in which the next generation grows.
Hebrews 13:4 says, “Let marriage be held in honor among all, and let the bed be undefiled; but God will judge the sexually immoral and adulterers.” That is a New Testament command standing directly on the seventh commandment, and it adds a sober warning. God will judge. This is not the severity of a harsh God; it is the seriousness of a faithful one. He takes marriage seriously enough to hold people accountable for it. The positive side of the verse is the call to honor marriage, which means treating it in our speech, humor, entertainment, and friendships as something precious rather than something to be mocked or exploited. Honoring marriage is a corporate calling. Churches honor marriage when they protect it and when they refuse to wink at what God says he will judge.
There is a practical edge to all of this. Guarding marriage is not only avoiding adultery; it is building the kind of relationship where adultery loses its appeal. Time, honesty, confession, prayer, and repentance repair the small distances that grow into large ones. Paul told husbands to love their wives as their own bodies and wives to respect their husbands. Those commands assume that marriages run down and need tending. A couple that prays together, speaks truthfully, and forgives often is not immune to temptation, but they are far less vulnerable. The seventh commandment invites us to build a life where fidelity is not merely avoided sin but a chosen, cultivated loyalty. That is a positive vision, not a cage.
Jesus Deepens the Command in the Sermon on the Mount
In Matthew 5:27-28 Jesus says, “You have heard that it was said, ‘You shall not commit adultery;’ but I tell you that everyone who gazes at a woman to lust after her has committed adultery with her already in his heart.” Jesus does not set aside the seventh commandment. He intensifies it. He moves the location of obedience from the hands to the heart, and in doing so he shuts the door on the self-congratulation of anyone who has never technically broken the command. This is characteristic of the Sermon on the Mount. Jesus does the same with murder and anger, with oaths and truthfulness, with love and enemies. The law was never meant to be a low bar that respectable people could clear. It was always meant to expose the heart.
The Greek word Jesus uses describes a continued, deliberate gazing, not the fleeting thought that a person refuses. There is a difference between a temptation that arrives uninvited and a fantasy that is entertained, rehearsed, and fed. Jesus is describing the second. That distinction is pastorally important, because many sincere Christians are tormented by intrusive thoughts they hate and never chose. The Lord is not condemning the man who recoils; he is naming the man who lingers. But we should be honest that the line is easy to blur. Pornography is adultery of the mind. Deliberate consumption of another person’s body for private pleasure is the very thing Jesus forbids, whether the woman is a neighbor or an image on a screen. The command reaches into what we do with our eyes.
Jesus then says something that sounds shocking: if your right eye causes you to stumble, tear it out; if your right hand causes you to stumble, cut it off. He is not teaching self-mutilation; the church has always read this as vivid hyperbole about the seriousness of sin. The point is that people will amputate a limb to save their life, and we should be willing to make drastic, costly changes to avoid sin. Apply that to the seventh commandment and it becomes very practical. If a job, a friendship, a phone, a habit, a late-night pattern, or a physical place is the doorway to adultery, remove it. Radical obedience is not legalism. It is the reasonable response of a person who takes Jesus at his word.
Jesus also brings the command into the arena of divorce in Matthew 19:9. He says that whoever divorces his wife, except for sexual immorality, and marries another, commits adultery. He is answering a question from the Pharisees about grounds for divorce, and he goes behind Moses to the creation design. His point is that divorce followed by remarriage, outside the exception he names, is itself adultery. This is a hard saying, and faithful Christians have differed on how to apply it, especially about the exception clause. What is clear is that Jesus treats marriage as far more than a contract that can be dissolved at will. He has no interest in the casual divorce culture that surrounds us or the casual affair culture behind it.
Adultery Destroys the One Who Does It
Proverbs devotes an entire chapter to the seductive woman and the man who follows her, and it says, as Proverbs 6:32-35 says, “He who commits adultery with a woman is void of understanding. He who does it destroys his own soul.” We tend to think of adultery as a sin against other people, and it is. But Proverbs presses further: it is self-destruction. The person who does it is described as lacking understanding, as one who does not see the road he is on. The consequences Proverbs names are poverty, dishonor, wounds, and a jealousy that cannot be appeased. These are not arbitrary divine punishments tacked onto an otherwise harmless pleasure. They are the natural harvest of a life that treats the deepest human covenant as disposable.
Notice the phrase, destroys his own soul. There is a peculiar self-harm in adultery that the person committing it often cannot see at the time. He may feel alive, desired, and important. But he is trading a real, lasting good for a momentary thrill, and he is training his own heart to lie, to divide, to live in shadow. He becomes someone he cannot fully face. He begins to justify, minimize, and blame, and each step hardens him. This is why Proverbs says he is void of understanding, not merely morally weak. He has lost the ability to see clearly. The path of adultery is a path of self-deception, and the worst damage is often to the deceiver himself. That is the sober testimony of Scripture, and it matches what we observe.
Proverbs also warns that the wound and dishonor are not easily erased, and that jealousy rages and no compensation will satisfy it. Some of the deepest, longest damage in families and churches comes from this sin precisely because it cannot simply be undone. Forgiveness from God is real and full, but consequences are not always reversed. Trust, once broken, is rebuilt slowly. Children may carry the memory for life. A reputation may be lost. This is why the New Testament says to flee sexual immorality, not to negotiate with it. Paul writes in 1 Corinthians 6:18, “Flee sexual immorality!” That verb is athletic and urgent. It is not the language of a person standing at a distance and considering options. It is the language of a person running for their life.
Paul goes on to say that other sins are outside the body, but the sexually immoral person sins against his own body, and he reminds the Corinthians that their bodies are members of Christ and temples of the Holy Spirit. He concludes, as 1 Corinthians 6:20 says, “For you were bought with a price. Therefore glorify God in your body.” This is the New Testament logic for the seventh commandment. We do not belong to ourselves. We were bought, and the price was the blood of Christ. That means the body is not a private playground but a place where God is honored or dishonored. This is not shame-based moralism; it is the dignity of redemption. The same Paul who warns so sternly writes elsewhere that some of the Corinthians had been sexually immoral and were washed, sanctified, and justified. Grace and holiness stand together.
Restoration for Adulterers and the Repentant
We must say plainly what the Bible says plainly: adultery is sin, God will judge the sexually immoral and adulterers, and no one is excused. We must also say plainly what the Bible says just as plainly: there is forgiveness with God, and no sinner who repents is beyond his mercy. David committed adultery with Bathsheba and arranged her husband’s death, and after the prophet Nathan confronted him he wrote Psalm 51, pleading for mercy and a clean heart. He was not spared consequences, but he was restored. The New Testament church in Corinth included people who had been sexually immoral, and Paul said they had been washed and sanctified in the name of the Lord Jesus Christ and by the Spirit of our God. That is not permission to sin; it is hope for the repentant.
Repentance in Scripture is specific. It means naming the sin honestly, taking responsibility rather than blaming circumstances or the other person, and turning from it. It often means confession to the people most affected and willingness to make restitution where possible. It may mean seeking help from a pastor or counselor, and it may mean ending contact with a person who has been part of the sin. It also means accepting that trust will need to be rebuilt over time and that some consequences will remain. Grace does not erase all earthly outcomes. But grace does what no amount of penance can do: it reconciles the sinner to God through Christ and gives a clean heart. That is worth more than every consequence avoided.
Those who have been sinned against need the same gospel, applied differently. Adultery wounds the betrayed spouse deeply, and Scripture does not ask them to pretend otherwise. Grief, anger, and confusion are normal. Forgiveness is a process and often a long one, and it does not require the wounded person to ignore the sin or to decide immediately about the future of the marriage. Some marriages, by God’s grace, are rebuilt stronger than before. Others are not, and Jesus himself names sexual immorality as a ground for divorce. Faithful Christians differ about the details, and we should not pretend the questions are simple. What we can say is that the church should surround the wounded, refuse to gossip about them, and offer both truth and compassion without pressure.
For those caught in a pattern of sexual sin, the way forward is the same as for every other sinner: run to Christ, not away from him. He is a merciful and faithful high priest, and he invites the weary to come. Confession to a trusted believer breaks the secrecy that feeds these sins. Accountability, honest prayer, and, where needed, professional help are means of grace, not works of penance. And there is a positive calling too: to build a life where loyalty to one’s spouse and to Christ is tended daily, where the eyes are guarded and the heart is filled with good things. The seventh commandment says, you shall not commit adultery, and behind the no stands a yes to a marriage that reflects the covenant love of God. That love is what we were made for.
Biblical fidelity check
What Exodus 20:14 does establish is clear. It forbids sexual relations between a married person and anyone other than their spouse, and it assumes the creation institution of marriage as God made it. It is spoken by God to a redeemed people, it is grounded in his covenant character, and it is deepened by Jesus, who locates the offense in the lustful heart, not only the act. Hebrews 13:4 adds that God will judge the sexually immoral and adulterers, so this is not a command he has quietly set aside under grace. What the command does not establish is a hierarchy of sins in which adultery is unforgivable, or a permission for the self-righteous to sneer at the fallen, or a claim that a person’s spiritual value before God rises and falls with their marital history. Scripture condemns the sin and welcomes the repentant sinner, with no contradiction.
A common misreading is to treat the seventh commandment as merely external, so that a person who has never physically committed adultery can feel fully obedient. Jesus dismantles that reading in Matthew 5:28, where he says the lustful gaze is adultery of the heart. Another misreading treats the command as nothing but a social rule about property and heirs that modern people have outgrown. That fails because Jesus, Paul, and the author of Hebrews all cite it as living moral authority, and because it rests on the creation order rather than on ancient culture. A third misreading assumes grace makes fidelity optional, which contradicts Paul’s warning that the unrighteous will not inherit the kingdom of God. The command is neither a low bar for the proud nor a club for the cruel, but a holy boundary spoken in love by a God who keeps covenant.

Frequently asked questions
Does Exodus 20:14 mean only married people can break it?
The command is addressed to the whole covenant community, not only the married. A single person who pursues or sleeps with someone else’s spouse breaks the same command. The unmarried are called to purity too, since Scripture forbids sexual immorality generally, not only adultery. So the seventh commandment protects marriage from every direction, including from the one who is not married. Nobody is outside its reach simply because they have no spouse. It is a community-wide call to honor the marriages around us and to keep our own bodies in holiness.
Is lust really the same as adultery?
Jesus says that whoever gazes at a woman to lust after her has already committed adultery in his heart. He is not saying a passing temptation is the same as an affair; he is naming the deliberate, entertained desire. The heart is where sin begins, and Jesus will not let us settle for external cleanliness. This is a call to guard the eyes and the imagination, to cut off what feeds lust, and to seek a clean heart from God. It is a searching word, but it is also a hopeful one, because God changes hearts.
Can a marriage survive adultery?
Yes, by God’s grace, many marriages have been rebuilt after adultery, sometimes with deeper honesty than before. But the Bible does not promise that every marriage will be restored, and Jesus names sexual immorality as a ground for divorce. The path forward requires genuine repentance from the one who sinned and time for trust to be rebuilt. Faithful Christians differ on some of these questions, and the church should be patient with the wounded rather than pressuring them. The gospel offers both holiness and mercy here.
