1 Corinthians 7:11-13

American Standard Version

¹¹ (but should she depart, let her remain unmarried, or else be reconciled to her husband); and that the husband leave not his wife. ¹² But to the rest say I, not the Lord: If any brother hath an unbelieving wife, and she is content to dwell with him, let him not leave her. ¹³ And the woman that hath an unbelieving husband, and he is content to dwell with her, let her not leave her husband.
