Marrying a Captive Woman
After victory in war, if an Israelite desires a captive woman, he must bring her into his house and wait. Her altered appearance, changed clothing, and month of mourning set this transition apart from immediate possession.
W10hen you go to war against your enemies and the LORD your God delivers them into your hand and you take them captive, 11if you see a beautiful woman among them, and you desire her and want to take her as your wife, 12then you shall bring her into your house. She must shave her head, trim her nails, 13and put aside the clothing of her captivity.
After her mourning, she may become his wife, but if he no longer wants her, he must release her freely. Because he has humbled her, he may not sell her or keep her as a slave.
14After she has lived in your house a full month and mourned her father and mother, you may have relations with her and be her husband, and she shall be your wife. And if you are not pleased with her, you are to let her go wherever she wishes. But you must not sell her for money or treat her as a slave, since you have dishonored her.
