Deuteronomy 21:10-14

“When you go out to battle against your enemies, and the LORD your God hands them over to you and you lead them away captive, and you see a beautiful woman among the captives, and desire her and would take her as your wife, then you shall bring her [home] to your house, and she shall shave her head and trim her nails [in preparation for mourning]. She shall take off the clothes of her captivity and remain in your house, and weep (mourn) for her father and her mother a full month. After that you may go in to her and be her husband and she shall be your wife. But it shall be that if you have no delight and take no pleasure in her, then you shall let her go wherever she wishes. You certainly shall not sell her for money; you shall not deal with her as a slave or mistreat her, because you have humbled her [by forced marriage].
