11 and see among the captives a beautiful woman, and you have a desire to her, and would take her to you as wife; 12 then you shall bring her home to your house; and she shall shave her head, and pare her nails; 13 and she shall put the clothing of her captivity from off her, and shall remain in your house, and bewail her father and her mother a full month: and after that you shall 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.
