Deuteronomy 21:8-14
English Standard Version
Chapter 21
8Accept atonement, O Lord, for your people Israel, whom you have redeemed, and do not set the guilt of innocent blood in the midst of your people Israel, so that their blood guilt be atoned for.’ 9So you shall purge the guilt of innocent blood from your midst, when you do what is right in the sight of the Lord.
10"When you go out to war against your enemies, and the Lord your God gives them into your hand and you take them captive,
11and you see among the captives a beautiful woman, and you desire to take her to be your wife,
12and you bring her home to your house, she shall shave her head and pare her nails.
13And she shall take off the clothes in which she was captured and shall remain in your house and lament 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.
14But if you no longer delight in her, you shall let her go where she wants. But you shall not sell her for money, nor shall you treat her as a slave, since you have humiliated her.
