In case anyone ever tries to tell you that Jewish rabbis have never understood Isaiah 53 as referring to the Messiah...

"The Rabbis said: His name is 'the leper scholar,' as it is written, Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him a leper, smitten of God, and afflicted."
Babylonian Talmud, Tractate Sanhedrin, Folio 98b

"Our righteous Messiah has turned away from us; we have acted foolishly and there is no one to justify us. Our iniquities and the yoke of our transgressions he bears, and he is pierced for our transgressions. He carries our sins on his shoulder, to find forgiveness for our iniquities."
R. Eliezer, Machzor Kol Bo

Maimonides wrote that '[The ancient Jews] believed that leprosy was one of the characteristics of the Messiah, for which they found an allusion to the verse: "stricken, smitten of God, and afflicted", that is by leprosy.'
