Deuteronomy 24:3-5

New Revised Standard Version Updated Edition

³ Then suppose the second man dislikes her, writes her a certificate of divorce, puts it in her hand, and sends her out of his house (or the second man who married her dies): ⁴ her first husband, who sent her away, is not permitted to take her again to be his wife after she has been defiled, for that would be abhorrent to the Lord, and you shall not bring guilt on the land that the Lord your God is giving you as a possession.^(A)

Miscellaneous Laws
