Deuteronomy 24:1-5 - Marriage And Divorce Laws
1 When a man taketh a woman, and marrieth her, then shall it be, if she find not favour in his eyes, because he hath found in her some matter of shame, that he shall write her a scroll of divorcement, and put it into her hand, and shall send her forth, out of his house. 2 And, when she cometh forth out of his house, then may she go her way, and become another man's. 3 But if the latter husband hate her, and write her a scroll of divorcement and put it into her hand, and send her away out of his house, - or, if the latter husband die, who had taken her to him to wife, 4 then may her first husband who sent her away not again take her to become his wife after that she hath been defiled, for that were an abomination, before Yahweh, - lest thou bring sin upon the land which Yahweh thy God is giving unto thee for an inheritance.
5 When a man taketh a new wife, he shall not go forth to war, neither shall he be charged with any business, - free, shall he be for his own house one year, and shall rejoice with his wife whom he hath taken.
