1 Coríntios 7

10 But to those already married my instructions are –yet not mine, but the Lord's– that a wife is not to leave her husband;

11 or if she has already left him, let her either remain as she is or be reconciled to him; and that a husband is not to send away his wife.

12 To the rest it is I who speak–not the Lord. If a brother has a wife who is an unbeliever, and she consents to live with him, let him not send her away.
