1 Corinthians 7:10-12

Living Bible

¹⁰ Now, for those who are married I have a command, not just a suggestion. And it is not a command from me, for this is what the Lord himself has said: A wife must not leave her husband. ¹¹ But if she is separated from him, let her remain single or else go back to him. And the husband must not divorce his wife.

¹² Here I want to add some suggestions of my own. These are not direct commands from the Lord, but they seem right to me: If a Christian has a wife who is not a Christian, but she wants to stay with him anyway, he must not leave her or divorce her.
