1 Corinthians 7:10-13

Darby(i) 10 But 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. 12 But 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. 13 And a woman who has an unbelieving husband, and he consents to dwell with her, let her not leave [her] husband.
