Deuteronomy 21:11-14

NSB(i) 11 »If you see a beautiful woman among the captives and your heart is set on her, you may marry her. 12 »Take her to your home. She should shave her head and cut her nails. 13 »She should no longer wear the clothes she was wearing when you captured her. She may live in your house and mourn the loss of her father and mother for one month. After that you may marry her. 14 »Later if you are not happy with the woman you may divorce her. She may go free. But you have slept with her as your wife, so you cannot sell her as a slave or make her into your own slave.
