Deuteronomy 24:1-5

New Century Version

24 A man might marry a woman but later decide she doesn’t please him because he has found something bad about her. He writes out divorce papers for her, gives them to her, and sends her away from his house. ² After she leaves his house, she goes and marries another man, ³ but her second husband does not like her either. So he writes out divorce papers for her, gives them to her, and sends her away from his house. Or the second husband might die. ⁴ In either case, her first husband who divorced her must not marry her again, because she has become unclean. The Lord would hate this. Don’t bring this sin into the land the Lord your God is giving you as your own.

⁵ A man who has just married must not be sent to war or be given any other duty. He should be free to stay home for a year to make his new wife happy.
