Deuteronomy 24:2-4

2and she leaves his house and goes and becomes another man’s wife, 3and the latter husband 1turns against her, writes her a certificate of divorce and puts it in her hand, and 2sends her away from his house, or if the latter husband who took her to be his wife dies, 4then her 3former husband who 4sent her away is not allowed to take her again to be his wife, after 5she 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.
