1 Coríntios 7

10 But to the married I give orders, though not I but the Lord, that the wife may not go away from her husband

11 (Or if she goes away from him, let her keep unmarried, or be united to her husband again); and that the husband may not go away from his wife.

12 But to the rest I say, and not the Lord; If a brother has a wife who is not a Christian, and it is her desire to go on living with him, let him not go away from her.
