Deuteronomy 21:12-14

New Revised Standard Version, Anglicised Catholic Edition

¹² and so you bring her home to your house: she shall shave her head, pare her nails, ¹³ discard her captive’s garb, and shall remain in your house for a full month, mourning for her father and mother; after that you may go in to her and be her husband, and she shall be your wife. ¹⁴ But if you are not satisfied with her, you shall let her go free and not sell her for money. You must not treat her as a slave, since you have dishonoured her.
