Deuteronomy 24:3-5

World English Bible

³ If the latter husband hates her, and write 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 Yahweh. You shall not cause the land to sin, which Yahweh 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.
