Deuteronomy 21:11-13

New American Standard Bible

¹¹ and you see among the captives a beautiful woman, and are strongly attracted to her and would take her as a wife for yourself, ¹² then you shall bring her into your home, and she shall ^(A)shave her head and ^[a]trim her nails. ¹³ She shall also ^[b]remove the clothes of her captivity and shall remain in your house, and ^(B)weep for her father and mother a full month; and after that you may have relations with her and become her husband and she shall be your wife.
