What the Bible says about adultery

1 Corinthians 6:9-11

Or don’t you know that the unrighteous will not inherit God’s Kingdom? Don’t be deceived. Neither the sexually immoral, nor idolaters, nor adulterers, nor male prostitutes, nor homosexuals, nor thieves, nor covetous, nor drunkards, nor slanderers, nor extortionists, will inherit God’s Kingdom. Such were some of you, but you were washed. But you were sanctified. But you were justified in the name of the Lord Jesus, and in the Spirit of our God.

Hebrews 13:4

Let marriage be held in honor among all, and let the bed be undefiled: but God will judge the sexually immoral and adulterers.

Proverbs 6:32-35

He who commits adultery with a woman is void of understanding. He who does it destroys his own soul. He will get wounds and dishonor. His reproach will not be wiped away. For jealousy arouses the fury of the husband. He won’t spare in the day of vengeance. He won’t regard any ransom, neither will he rest content, though you give many gifts.

1 Corinthians 7:2-5

But, because of sexual immoralities, let each man have his own wife, and let each woman have her own husband. Let the husband give his wife the affection owed her, and likewise also the wife her husband. The wife doesn’t have authority over her own body, but the husband. Likewise also the husband doesn’t have authority over his own body, but the wife. Don’t deprive one another, unless it is by consent for a season, that you may give yourselves to fasting and prayer, and may be together again, that Satan doesn’t tempt you because of your lack of self-control.

James 1:14-15

But each one is tempted when he is drawn away by his own lust, and enticed. Then the lust, when it has conceived, bears sin; and the sin, when it is full grown, produces death.

John 8:1-11

but Jesus went to the Mount of Olives. Now very early in the morning, he came again into the temple, and all the people came to him. He sat down, and taught them. The scribes and the Pharisees brought a woman taken in adultery. Having set her in the middle, they told him, “Teacher, we found this woman in adultery, in the very act. Now in our law, Moses commanded us to stone such women. What then do you say about her?” They said this testing him, that they might have something to accuse him of. But Jesus stooped down, and wrote on the ground with his finger. But when they continued asking him, he looked up and said to them, “He who is without sin among you, let him throw the first stone at her.” Again he stooped down, and with his finger wrote on the ground. They, when they heard it, being convicted by their conscience, went out one by one, beginning from the oldest, even to the last. Jesus was left alone with the woman where she was, in the middle. Jesus, standing up, saw her and said, “Woman, where are your accusers? Did no one condemn you?” She said, “No one, Lord.” Jesus said, “Neither do I condemn you. Go your way. From now on, sin no more.”
