And she shall put the clothing of her captivity from off her, and shall remain in your house, and mourn her father and her mother a full month: and after that you shall go in unto her, and be her husband, and she shall be your wife.
All Commentaries on Deuteronomy 21:13 Go To Deuteronomy 21
Clement Of Alexandria
AD 215
The [Deuteronomic] law wishes males to have responsible sexual relations with their marriage partners, solely for the generation of children. This is clear when a bachelor is prevented from enjoying immediate sexual relations with a woman prisoner of war. If he once falls in love with her, he must let her cut her hair short and mourn for thirty days. If even so his desire has not faded away, then he may father children by her. The fixed period of time enables the overpowering impulse to be scrutinized and to turn into a more rational appetency.
