1 Corinthians 7:10

³²but I tell you that whoever puts away his wife, except for the cause of sexual immorality, makes her an adulteress; and whoever marries her when she is put away commits adultery.

¹⁸“Everyone who divorces his wife and marries another commits adultery. He who marries one who is divorced from a husband commits adultery.

³Pharisees came to him, testing him and saying, “Is it lawful for a man to divorce his wife for any reason?”

⁴He answered, “Haven’t you read that he who made them from the beginning made them male and female,⁵and said, ‘For this cause a man shall leave his father and mother, and shall be joined to his wife; and the two shall become one flesh’?⁶So that they are no more two, but one flesh. What therefore God has joined together, don’t let man tear apart.”

⁷They asked him, “Why then did Moses command us to give her a certificate of divorce and divorce her?”

⁸He said to them, “Moses, because of the hardness of your hearts, allowed you to divorce your wives, but from the beginning it has not been so. ⁹I tell you that whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and he who marries her when she is divorced commits adultery.”

¹⁴Yet you say, ‘Why?’ Because the LORD has been witness between you and the wife of your youth, against whom you have dealt treacherously, though she is your companion and the wife of your covenant. ¹⁵Did he not make you one, although he had the residue of the Spirit? Why one? He sought godly offspring. Therefore take heed to your spirit, and let no one deal treacherously against the wife of his youth. ¹⁶One who hates and divorces”, says the LORD, the God of Israel, “covers his garment with violence!” says the LORD of Armies. “Therefore pay attention to your spirit, that you don’t be unfaithful.

¹¹He said to them, “Whoever divorces his wife and marries another commits adultery against her. ¹²If a woman herself divorces her husband and marries another, she commits adultery.”

¹⁵Yet if the unbeliever departs, let there be separation. The brother or the sister is not under bondage in such cases, but God has called us in peace.

²⁰“Surely as a wife treacherously departs from her husband, so you have dealt treacherously with me, house of Israel,” says the LORD.

¹²But to the rest I—not the Lord—say, if any brother has an unbelieving wife, and she is content to live with him, let him not leave her.

²⁵Now concerning virgins, I have no commandment from the Lord, but I give my judgment as one who has obtained mercy from the Lord to be trustworthy.

⁶But this I say by way of concession, not of commandment.
