11 and hast seen in the captivity a woman of fair form, and hast delighted in her, and hast taken to thee for a wife, 12 then thou hast brought her in unto the midst of thy household, and she hath shaved her head, and prepared her nails, 13 and turned aside the raiment of her captivity from off her, and hath dwelt in thy house, and bewailed her father and her mother a month of days, and afterwards thou dost go in unto her and hast married her, and she hath been to thee for a wife:

Commentary on Deuteronomy 21:10-14

(Read Deuteronomy 21:10-14)
