And as noted by Jewish scholar Claude Montefiore, Isaiah 53 is rarely found in any Rabbinic literature.
Quotations from the famous 53rd chapter of Isaiah are rare in Rabbinic literature.
[Because of the christological interpretation given to the chapter by Christians, it is omitted from the series of prophetical lessons (Haftarot) for the Deuteronomy Sabbaths. These seven lessons a called the *Seven (Chapters) of Comfort’, and are taken from the preceding and following parts of the book: the omission is deliberate and striking. (H. L.)]
