Deuteronomy 24:1-4

Living Bible

24 “If a man doesn’t like something about his wife, he may write a letter stating that he has divorced her, give her the letter, and send her away. ² If she then remarries ³ and the second husband also divorces her or dies, ⁴ the former husband may not marry her again, for she has been defiled; this would bring guilt upon the land the Lord your God is giving you.
