תּלמוד אויף ישעיהו 26:6

But this "footgoing times," is needed to exempt men with wooden legs! This comes out of "pe'amim" [which can be translated both as "times" and "steps"], for it is taught in a Baraita: "Pe'amim" refers not to "times" but "feet", and so it says, (Isaiah 26:6) "The foot shall tread it down, the feet of the poor, the feet ("pe'amei") of the needy," and it says, (Song of Songs 7:2) "How beautiful are your feet (pa'amech") in shoes, O prince's daughter!"
