Deuteronomy 24:1-5 King James Version (KJV)
24 When a man hath taken a wife, and married her, and it come to pass that she find 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.
2 And when she is departed out of his house, she may go and be another man's wife.
3 And if the latter husband hate her, and write her a bill of divorcement, and giveth it in her hand, and sendeth her out of his house; or if the latter husband die, which took her to be his wife;
4 Her former husband, which 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.
5 When a man hath taken a new 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 up his wife which he hath taken.
