Deuteronomy 24:2-4

And when she is departed out of his house, she may go and be another man’s wife. And if the latter husband 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 die, who took her to be his wife; her 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 Jehovah: and thou shalt not cause the land to sin, which Jehovah thy God giveth thee for an inheritance.
