Deuteronomy 24:1-4
Law of Divorce
1 “When a man takes a wife and marries her, and it happens that she (a)loses his favor because he has found something indecent or unacceptable about her, and he writes her a certificate of divorce, puts it in her hand and sends her out of his house,
2 and after she leaves his house, she goes and becomes another man’s wife,
3 and if the latter husband (b)turns against 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 then her former husband who [first] sent her away may not take her again as his wife, since she has been defiled; for that is an outrage before the Lord, and you shall not bring sin on the land which the Lord your God gives you as an inheritance.
