1 Corinthians 7:10-17

10To the married I give this command  — not I, but the Lord — a wife is not to leave her husband.

11But if she does leave, she must remain unmarried or be reconciled to her husband — and a husband is not to divorce his wife.

12But I (not the Lord) say to the rest: If any brother has an unbelieving wife and she is willing to live with him, he must not divorce her.

13Also, if any woman has an unbelieving husband and he is willing to live with her, she must not divorce her husband.

14For the unbelieving husband is made holy by the wife, and the unbelieving wife is made holy by the husband. Otherwise your children would be unclean, but as it is they are holy.

15But if the unbeliever leaves, let him leave. A brother or a sister is not bound in such cases. God has called you to live in peace.

16Wife, for all you know, you might save your husband. Husband, for all you know, you might save your wife.

17Let each one live his life in the situation the Lord assigned when God called him. This is what I command in all the churches.
