Let marriage be held in honor among all, and let the marriage bed be undefiled, for God will judge the sexually immoral and adulterous.
You shall not commit adultery.
He who commits adultery lacks sense; he who does it destroys himself.
And I say to you: whoever divorces his wife, except for sexual immorality, and marries another, commits adultery.
“You have heard that it was said, ‘You shall not commit adultery.’ But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart."
1 Corinthians 6:18
Flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body.
If a man commits adultery with the wife of his neighbor, both the adulterer and the adulteress shall surely be put to death.
Everyone who divorces his wife and marries another commits adultery, and he who marries a woman divorced from her husband commits adultery.
If a man is found lying with the wife of another man, both of them shall die, the man who lay with the woman, and the woman. So you shall purge the evil from Israel.
1 Corinthians 6:9-10
Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God.
Now the works of the flesh are evident: sexual immorality, impurity, sensuality,
1 Corinthians 10:13
No temptation has overtaken you that is not common to man. God is faithful, and he will not let you be tempted beyond your ability, but with the temptation he will also provide the way of escape, that you may be able to endure it.
“It was also said, ‘Whoever divorces his wife, let him give her a certificate of divorce.’ But I say to you that everyone who divorces his wife, except on the ground of sexual immorality, makes her commit adultery, and whoever marries a divorced woman commits adultery."
So whoever knows the right thing to do and fails to do it, for him it is sin.
“For the man who does not love his wife but divorces her, says the Lord, the God of Israel, covers his garment with violence, says the Lord of hosts. So guard yourselves in your spirit, and do not be faithless.”
She saw that for all the adulteries of that faithless one, Israel, I had sent her away with a decree of divorce. Yet her treacherous sister Judah did not fear, but she too went and played the whore.
For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false witness, slander.
And he said to them, “Whoever divorces his wife and marries another commits adultery against her, and if she divorces her husband and marries another, she commits adultery.”
For they have committed adultery, and blood is on their hands. With their idols they have committed adultery, and they have even offered up to them for food the children whom they had borne to me.
1 John 1:9
If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
