Deuteronomy 21:12-14

Living Bible

¹² take her home with you. She must shave her head and pare her nails ¹³ and change her clothing, laying aside that which she was wearing when she was captured, then remain in your home in mourning for her father and mother for a full month. After that you may marry her. ¹⁴ However, if after marrying her you decide you don’t like her, you must let her go free—you may not sell her or treat her as a slave, for you have humiliated her.
