Deuteronomy 24:1-5

1When a man hath taken a wife, and married her, and it shall come to pass that she findeth no favour in his eyes, because he hath found some uncleanness in her: then let him write her a bill of divorcement, and give it in her hand, and send her out of his house.12 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.

5When a man hath newly taken a wife, he shall not go out to war, neither shall he be charged with any business: but he shall be free at home one year, and shall cheer his wife whom he hath taken.3
