Deuteronomy 24:1-4

1When a man taketh a wife, and marrieth her, it shall be if she find no favour in his eyes, because he hath found some unseemly thing in her, that he shall write her a letter of divorce, and give it into her hand, and send her out of his house.

2And she shall depart out of his house, and go away, and may become another man's wife.

3And if the latter husband hate her, and write her a letter of divorce, and give it into her hand, and send her out of his house; or if the latter husband die who took her as his wife;

4her first husband, who sent her away, may not take her again to be his wife, after that she is defiled; for it is an abomination before Jehovah; and thou shalt not cause the land to sin, which Jehovah thy 1God giveth thee for an inheritance.
