10To the married I give this command (not I, but the Lord): A wife must not separate from her husband.
11But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife.
12To the rest I say this (I, not the Lord): If a brother has an unbelieving wife and she is willing to live with him, he must not divorce her.
