Deuteronomy 21:11-13

Complete Jewish Bible

¹¹ and you see among the prisoners a woman who looks good to you, and you feel attracted to her and want her as your wife; ¹² you are to bring her home to your house, where she will shave her head, cut her fingernails ¹³ and remove her prison clothing. She will stay there in your house, mourning her father and mother for a full month; after which you may go in to have sexual relations with her and be her husband, and she will be your wife.
