Deuteronomy 24:2-4

New King James Version

² when she has departed from his house, and goes and becomes another man’s wife, ³ if the latter husband detests 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 (A)then her former husband who divorced her must not take her back to be his wife after she has been defiled; for that is ^[a]an abomination before the Lord, and you shall not bring sin on the land which the Lord your God is giving you as an inheritance.
