1 Corinthians 7:10-12

New Century Version

¹⁰ Now I give this command for the married people. (The command is not from me; it is from the Lord.) A wife should not leave her husband. ¹¹ But if she does leave, she must not marry again, or she should make up with her husband. Also the husband should not divorce his wife.

¹² For all the others I say this (I am saying this, not the Lord): If a Christian man has a wife who is not a believer, and she is happy to live with him, he must not divorce her.
