1 Corinthians 7:10-17

10But to the married I enjoin, not I, but the Lord, Let not wife be separated from husband;

11(but if also she shall have been separated, let her remain unmarried, or be reconciled to her husband;) and let not husband leave wife.

12But as to the rest, I say, not the Lord, If any brother have an unbelieving wife, and she consent to dwell with him, let him not leave her.

13And a woman who has an unbelieving husband, and he consents to dwell with her, let her not leave [her] husband.

14For the unbelieving husband is sanctified in the wife, and the unbelieving wife is sanctified in the brother; since [otherwise] indeed your children are unclean, but now they are holy.

15But if the unbeliever go away, let them go away; a brother or a sister is not bound in such [cases], but 1God has called us in peace.

16For what knowest thou, O wife, if thou shalt save thy husband? or what knowest thou, O husband, if thou shalt save thy wife?

17However, as the Lord has divided to each, as 2God has called each, so let him walk; and thus I ordain in all the assemblies.
