Deuteronomy 25:11

This Law is apparently harsh, but its severity skews how very pleasing to God is modesty, whilst, on the other hand, He abominates indecency; for, if in the heat of a quarrel, when the agitation of the mind is an excuse for excesses, it was a crime thus heavily punished, for a woman to take hold of the private parts of a man who was not her husband, much less would God have her lasciviousness pardoned, if a woman were impelled by lust to do anything of the sort. Neither can we doubt but that the judges, in punishing obscenity, were bound to argue from the less to the greater. A threat is also added, lest the severity of the punishment should influence their minds to be tender and remiss ill inflicting it. It was indeed inexcusable effrontery, willfully to assail that part of the body, from the sight and touch of which all chaste women naturally recoil.
