Deuteronomy 21:10-14

VIN(i) 10 When you go out to battle against your enemies, and the LORD your God delivers them into your hands and you carry them away captive, 11 and see among the captives a beautiful woman, and you are attracted to her, and desire to take her as your wife, 12 Bring her to your house, but shave her head and trim her nails. 13 and she shall remove the clothing she was wearing when captured, and shall remain in your house, and mourn her father and her mother a full month. And after that you may go in to her and be her husband, and she shall be your wife. 14 If you aren't pleased with her and you send her away, you must not sell her for money or mistreat her, since you have dishonored her."
