Deuteronomy 24:4 in the King James Version
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.
Context
3 If the latter husband hates her, and writes her a certificate of divorce, puts it in her hand, and sends her out of his house; or if the latter husband dies, who took her to be his wife;
4 her former husband, who sent her away, may not take her again to be his wife after she is defiled; for that would be an abomination to the LORD. You shall not cause the land to sin, which the LORD your God gives you for an inheritance.
5 When a man takes a new wife, he shall not go out in the army, neither shall he be assigned any business. He shall be free at home one year, and shall cheer his wife whom he has taken.
