Deuteronomy 24:1-5

When a man taketh a wife, and marrieth her, then it shall be, if she find no favor in his eyes, because he hath found some unseemly thing in her, that he shall write her a bill of divorcement, and give it in her hand, and send her out of his house. 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. When a man taketh a new wife, he shall not go out in the host, neither shall he be charged with any business: he shall be free at home one year, and shall cheer his wife whom he hath taken.
