Ezec 44.22Neither shall they take for their wives a widow, nor her that is put away: but they shall take maidens of the seed of the house of Israel, or a widow that had a priest before.
Deut 24.1-2When a man hath taken a wife, and married her, and it come to pass that she find no favor in his eyes, because he hath found some uncleanness in her: then let him write her a bill of divorcement, and give it in her hand, and send her out of his house.
