11 and you see among the captives a beautiful woman, and you desire to take her to be your wife, 12 and you bring her home to your house, she shall shave her head and pare her nails. 13 And she shall take off the clothes in which she was captured and shall remain in your house and lament her father and her mother a full month. After that you may go in to her and be her husband, and she shall be your wife.
Matthew Henry's Commentary on Deuteronomy 21:11-13
Commentary on Deuteronomy 21:10-14
(Read Deuteronomy 21:10-14)
By this law a soldier was allowed to marry his captive, if he pleased. This might take place upon some occasions; but the law does not show any approval of it. It also intimates how binding the laws of justice and honour are in marriage; which is a sacred engagement.
