Deuteronomy 21:11-13

Revised Standard Version

¹¹ and see among the captives a beautiful woman, and you have desire for her and would take her for yourself as wife, ¹² then you shall bring her home to your house, and she shall shave her head and pare her nails. ¹³ And she shall put off her captive’s garb, and shall remain in your house and bewail 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.
