Deuteronomy 24:3-5

Amplified Bible

³ and if the latter husband ^[a]turns against 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 as his wife, ⁴ then her former husband who [first] sent her away may not take her again as his wife, since she has been defiled; for that is an outrage before the Lord, and you shall not bring sin on the land which the Lord your God gives you as an inheritance.

⁵ “When a man takes a new wife, he shall not go out [to fight] with the army nor be charged with any duty; he shall be free at home for one year and shall bring happiness to his wife whom he has taken.
