Adultery is one of the most sensitive and serious topics discussed in Scripture. It not only breaks the bond between husband and wife, but also goes against God’s plan for covenant relationships.
In today’s world, where unfaithfulness is often normalized or even justified, the Bible still stands as a clear guide on what it means to remain faithful — not just physically, but in heart and spirit.
But the Bible doesn’t only warn against adultery. It also offers hope, healing, and forgiveness to those who have fallen, and guidance to those seeking to walk in purity. This post will take you through 17 Bible verses about adultery, exploring what they teach us about faithfulness, sin, repentance, and God’s restoring grace.
Whether you are seeking understanding, dealing with betrayal, or simply want to stay grounded in truth — this post is for you.
What Is Adultery According to the Bible?
In the Bible, adultery is defined as sexual relations between a married person and someone who is not their spouse. But Jesus expanded this definition to include even the thoughts and intentions of the heart.
🟤 Old Testament View:
Adultery was treated as a serious offense, often punishable by death under the Law of Moses (Leviticus 20:10). It was seen not just as a betrayal of a spouse, but as a rebellion against God’s law and a violation of the sacred covenant of marriage.
🟤 New Testament View:
Jesus raised the standard even higher. In Matthew 5:27–28, He says:
“You have heard that it was said, ‘You shall not commit adultery.’ But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.”
This shows that adultery is not only physical — it’s also emotional and spiritual. It’s about where your eyes go, what your heart desires, and where your loyalty lies.
Why God Takes Adultery Seriously
Marriage in Scripture is more than a human contract. It’s a spiritual covenant, a reflection of God’s relationship with His people.
When someone commits adultery, it’s a break in trust, unity, and purity — all of which God values deeply.
But here’s the hope: God’s Word not only reveals the danger of adultery, it also reveals the path to healing and forgiveness.
17 Bible Verses About Adultery and What They Teach Us About Faithfulness and Forgiveness
will begin exploring the actual Bible verses About Adultery and What They Teach Us About Faithfulness and Forgiveness below.
1. Exodus 20:14 – “You shall not commit adultery.”
This is the seventh commandment in the Ten Commandments. It’s a direct, non-negotiable instruction from God to His people.
🔍 What It Teaches:
God values marital fidelity. Adultery is not just a sin against a spouse — it’s a sin against God. This commandment forms the moral foundation for the sanctity of marriage throughout the Bible.
🙏 Reflection:
Faithfulness is God’s design. Keeping your marriage covenant is not only a commitment to your spouse but a sign of obedience to God.
2. Leviticus 20:10 – Adultery and Its Consequences
“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.”
🔍 What It Teaches:
This law from the Old Testament underscores how seriously God regarded adultery among His covenant people. Though we are no longer under the Law, this verse reveals how deeply God values purity and trust in marriage.
🙏 Reflection:
Though we may not face physical punishment today, adultery still brings emotional and spiritual consequences. But God also offers grace to those who repent.
3. Proverbs 6:32 – Adultery Is Self-Destructive
“But a man who commits adultery has no sense; whoever does so destroys himself.”
🔍 What It Teaches:
Adultery is not just a betrayal — it’s self-inflicted harm. It can destroy families, reputations, and a person’s own sense of worth and peace.
🙏 Reflection:
Before giving in to temptation, consider the long-term consequences. God’s way is not to restrict joy, but to protect it.
4. Proverbs 5:3-5 – The Bitter End of Temptation
“For the lips of the adulterous woman drip honey, and her speech is smoother than oil; but in the end she is bitter as gall, sharp as a double-edged sword.”
🔍 What It Teaches:
Adultery often starts with sweet words and secret attraction, but its end is painful. The Bible gives a sober warning against being deceived by temporary pleasure.
🙏 Reflection:
Temptation may appear attractive at first, but God’s Word exposes the end result — bitterness, regret, and separation from His best.
5. Job 31:1 – A Covenant With the Eyes
“I made a covenant with my eyes not to look lustfully at a young woman.”
🔍 What It Teaches:
Job shows us that guarding your eyes is part of remaining faithful. Lust is often the first step toward adultery — in thought or action.
🙏 Reflection:
Faithfulness starts with your heart and your eyes. Be intentional about what you feed your mind. Pray for self-control and purity.
6. Deuteronomy 5:18 – Reaffirming God’s Command
“You shall not commit adultery.”
🔍 What It Teaches:
This is a second mention of the commandment in Scripture. God reaffirms His laws to Israel before they enter the Promised Land — showing that faithfulness is a timeless standard, not a cultural suggestion.
🙏 Reflection:
God’s Word doesn’t change with trends or opinions. Marital faithfulness is still His standard for believers today.
7. Malachi 2:14-16 – God Hates Divorce and Unfaithfulness
“The Lord is the witness between you and the wife of your youth. You have been unfaithful to her… So be on your guard, and do not be unfaithful.”
🔍 What It Teaches:
God views marriage as a sacred covenant — one He personally witnesses. Unfaithfulness grieves His heart. He desires commitment, love, and loyalty in marriage.
🙏 Reflection:
Be faithful not only in action but in heart and attitude. Invite God to strengthen your marriage and help you honor your vows.
8. Matthew 5:27–28 – Adultery Begins in the Heart
“You have heard that it was said, ‘You shall not commit adultery.’ But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.”
🔍 What It Teaches:
Jesus doesn’t just deal with outward actions — He goes deeper to the heart. Lustful thoughts are just as serious to God as physical adultery. This verse calls us to a higher level of purity and self-awareness.
🙏 Reflection:
Guard your thoughts. Ask the Holy Spirit to purify your desires and renew your mind with His truth. What starts in the heart eventually shows in behavior.
9. Matthew 19:9 – Jesus on Divorce and Sexual Sin
“I tell you that anyone who divorces his wife, except for sexual immorality, and marries another woman commits adultery.”
🔍 What It Teaches:
Jesus addresses the serious nature of marital vows. Sexual unfaithfulness is a deep breach of covenant, and it can have lasting relational and spiritual consequences.
🙏 Reflection:
Marriage is not a casual contract — it’s a lifelong covenant. If you’re married, pray for strength to protect your relationship. If you’re healing from betrayal, know that God sees and understands your pain.
10. John 8:3–11 – Mercy for the Woman Caught in Adultery
“Neither do I condemn you,” Jesus declared. “Go now and leave your life of sin.”
🔍 What It Teaches:
This moment is full of truth and grace. Jesus does not ignore the woman’s sin, but He also doesn’t condemn her. He offers forgiveness and the power to live differently. This is the Gospel at work.
🙏 Reflection:
If you’ve fallen, there is forgiveness. Jesus does not cast you away. He gives you a new beginning. Accept His mercy, and walk in freedom.
11. Romans 13:9 – Love Fulfills the Law
“You shall not commit adultery… and whatever other command there may be, are summed up in this one command: ‘Love your neighbor as yourself.’”
🔍 What It Teaches:
When we truly love others — including our spouses — we don’t betray them. Adultery is a failure of love. True love is faithful, sacrificial, and protective.
🙏 Reflection:
Ask God to fill your heart with His kind of love — the love that honors others, stays loyal, and reflects Christ.
12. Hebrews 13:4 – Honor the Marriage Bed
“Marriage should be honored by all, and the marriage bed kept pure, for God will judge the adulterer and all the sexually immoral.”
🔍 What It Teaches:
Marriage is sacred. It is not to be treated lightly or defiled. This verse is a reminder that God sees what happens in secret, and He calls us to sexual purity both in thought and behavior.
🙏 Reflection:
Honor your marriage and others’ marriages. If you’re single, pray now for purity and integrity. If you’re married, ask God to protect and strengthen your relationship daily.
13. 1 Corinthians 6:9–10 – Adultery Among Other Sins
“Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers… will inherit the kingdom of God.”
🔍 What It Teaches:
This sobering warning reminds us that persistent, unrepentant sin separates us from God. Adultery is listed among sins that should not characterize the lives of believers.
🙏 Reflection:
Repentance is the key. No matter your past, God’s grace is available when you turn from sin and choose to follow Him.
14. 1 Corinthians 6:18 – Flee from Sexual Immorality
“Flee from sexual immorality. All other sins a person commits are outside the body, but whoever sins sexually, sins against their own body.”
🔍 What It Teaches:
We are not told to reason with sexual sin — we are told to run from it. Sexual sin affects you at a deep level — emotionally, spiritually, and physically.
🙏 Reflection:
Don’t put yourself in compromising situations. Flee. Guard your heart, your eyes, and your body. Walk in purity, with God’s help.
15. James 4:4 – Spiritual Adultery
“You adulterous people, don’t you know that friendship with the world means enmity against God?”
🔍 What It Teaches:
Adultery isn’t always about marriage. Spiritual adultery happens when we turn our hearts away from God and chase after worldly things. It’s a betrayal of our covenant with Him.
🙏 Reflection:
Examine your loyalties. Is God your first love? If anything has taken His place in your heart, repent and return.
16. Revelation 2:22 – Consequences of Immorality
“So I will cast her on a bed of suffering, and I will make those who commit adultery with her suffer intensely, unless they repent of her ways.”
🔍 What It Teaches:
Jesus gave this warning to the church in Thyatira. It shows that God holds even churches accountable for tolerating sexual immorality. Yet His call is always to repentance.
🙏 Reflection:
If sin has been ignored or justified, now is the time to confess it and seek God’s mercy. He offers a way out for all who turn back to Him.
17. Psalm 51:1–4 – David’s Repentance
“Have mercy on me, O God… Against you, you only, have I sinned and done what is evil in your sight.”
🔍 What It Teaches:
After committing adultery with Bathsheba, King David broke and repented. This psalm shows what true repentance looks like — not excuses, but a heart that grieves over sin and longs to be restored.
🙏 Reflection:
No matter how far you’ve fallen, God’s mercy is greater. When you confess with a sincere heart, He forgives, restores, and renews your spirit.
What These Verses Teach Us About Faithfulness
Faithfulness is more than avoiding physical adultery — it’s a posture of the heart. The Bible shows that God honors those who stay committed to their covenant, whether in marriage or in their relationship with Him.
Here’s what we learn:
Faithfulness is a reflection of God’s own character.
Loyalty in marriage builds spiritual strength and trust.
Our thoughts and emotional connections matter — not just physical acts.
God desires purity, commitment, and sincere love in our relationships.
What These Verses Teach Us About Forgiveness and Restoration
The Bible doesn’t just warn — it restores.
These scriptures prove that:
Adultery is not the end of the story for those who repent.
God’s mercy is deeper than our deepest mistake.
David was restored. The woman caught in adultery was forgiven.
God’s grace can heal broken marriages, comfort the betrayed, and transform the heart of the unfaithful.
Can God Forgive Adultery?
Absolutely.
God can forgive any sin — including adultery — when there is true repentance. David’s story in Psalm 51 is proof. Jesus’ response to the woman in John 8 confirms it. 1 John 1:9 reminds us:
“If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.”
Forgiveness may not erase earthly consequences, but it opens the door to healing, restoration, and peace with God.

Invest in your marriage – Communicate, pray together, and stay emotionally connected.
Seek accountability – A trusted believer can help you stay on track when you’re tempted.
Remember: Faithfulness is a daily decision, empowered by the Holy Spirit.
