Clement of Alexandria : 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. — The Stromata Book 3
