Deuteronomy 24:1-5

1“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 1indecency in her, that 2he writes her a certificate of divorce, puts it in her hand, and 3sends her away from his house, 2and she leaves his house and goes and becomes another man’s wife, 3and the latter husband 4turns against her, writes her a certificate of divorce and puts it in her hand, and 5sends her away from his house, or if the latter husband who took her to be his wife dies, 4then her 6former husband who 7sent her away is not allowed to take her again to be his wife, after 8she 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.

5“9When a man takes a new wife, he is not to go out with the army, nor be assigned any duty; he shall be free at home for one year and shall 10make his wife whom he has taken happy.
