Deuteronomy 21:12-14

New Catholic Bible

¹² Bring her into your house, and have her shave her head and trim her nails ¹³ and have her throw out the clothes she was wearing when she was taken captive. She is to live in your house for a full month and mourn her father and her mother. Then you may go to her and be her husband and she will be your wife. ¹⁴ If you are not pleased with her, you are to let her go wherever she wishes. You are not to sell her or treat her like a slave, for you have already humbled her.
