Deuteronomy 24:1-4

“When a man takes a wife and marries her, and it happens, if she finds no favor in his eyes because he has found some indecency in her, that he writes her a certificate of divorce, puts it in her hand, and sends her away from his house,

and she leaves his house and goes and becomes another man’s wife,

and the latter husband turns against her, writes her a certificate of divorce and puts it in her hand, and sends her away from his house, or if the latter husband who took her to be his wife dies,

then her former husband who sent her away is not allowed to take her again to be his wife, after she has been defiled; for that is 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.
