Deuteronomy 24:2-4

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.
