1 Corinthians 7:10-14

10I pass this command along (not really I, but the Lord): A wife shouldn’t leave her husband.

11If she does, she should stay single or make up with her husband. Likewise, a husband should not divorce his wife.

12I (not the Lord) say to the rest of you: If any Christian man is married to a woman who is an unbeliever, and she is willing to live with him, he should not divorce her.

13If any Christian woman is married to a man who is an unbeliever, and he is willing to live with her, she should not divorce her husband.

14Actually, the unbelieving husband is made holy because of his wife, and an unbelieving wife is made holy because of her husband. Otherwise, their children would be unacceptable ⌞to God⌟, but now they are acceptable to him.
