DEUT1239 Regarding sight, they of blessed memory have said (Berachos 61a): "'[From] hand to hand, the evil will not be cleansed' (Mishlei 11:21) means that anyone who counts out coins from his hand to hers in order to gaze upon her will not be cleansed from the judgment of Gehinom." And they also said (Shabbos 64a): "Why did the Israelites of that generation require atonement? Because they feasted their eyes on promiscuity." "Rav Sheshes said: Why does Scripture enumerate the jewelry that is [worn] externally together with the jewelry that is [worn] under [one's clothing]? It wants to teach us that anyone who gazes at [even] the small finger of a woman is regarded as having gazed at her impurity (Berachos 24a). And they also said (Avodah Zarah 20a): "You shall be careful of all evil things' [this verse] means that one should not gaze at a beautiful woman even if she is unmarried [nor] at a married woman even if she is ugly."
