1 Corinthians 7:10-14

Williams(i) 10 To the people already married I give this instruction -- no, not I but the Lord -- that a wife is not to leave her husband. 11 But if she does leave him, she must remain single, or better, be reconciled to her husband. I instruct the husband too not to divorce his wife. 12 To the rest of the people I myself would say -- though the Lord Himself has said nothing about it -- if a Christian has a wife that is not a believer and she consents to live with him, he must not divorce her; 13 and a woman who has a husband that is not a believer, but he consents to live with her, must not divorce her husband. 14 For the unbelieving husband is consecrated by union with his wife and the unbelieving wife by union with her Christian husband, for otherwise your children would be unblessed, but in this way they are consecrated.
