Deuteronomy 24:2-4

2And when she hath departed from his house, she may go and be another man’s wife . 3And if the latter husband shall hate her, and write her a bill of divorcement, and give it in her hand, and send her out of his house; or if the latter husband shall die, who took her to be his wife; 4Her former husband, who sent her away, may not take her again to be his wife, after that she is defiled; for that is abomination before the LORD: and thou shalt not cause the land to sin, which the LORD thy God giveth thee for an inheritance.
