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:

Matthew Henry's Commentary on Deuteronomy 21:13

Commentary on Deuteronomy 21:10-14

(Read Deuteronomy 21:10-14)
