Deuteronomy 25:12

Partly because of the great mischief she did to him, both to his person and posterity, and partly to deter all women from all immodest and impudent carriages, and to secure that modesty which is indeed the guardian of all the virtues, as immodesty is an inlet to all vices, as the sad experience of this degenerate age shows; and therefore it is not strange that it is so severely restrained and punished. Thine eye shall not pity her, which thou wilt be very apt to do, because of the infirmity of her sex, and the urgency of the occasion, this being done for the necessary preservation of her husband.
