Deuteronomy 24:3-5

New Living Translation

³ But if the second husband also turns against her, writes a document of divorce, hands it to her, and sends her away, or if he dies, ⁴ the first husband may not marry her again, for she has been defiled. That would be detestable to the Lord. You must not bring guilt upon the land the Lord your God is giving you as a special possession.

⁵ “A newly married man must not be drafted into the army or be given any other official responsibilities. He must be free to spend one year at home, bringing happiness to the wife he has married.
