Circumcision and the foreskin
Synopsis
Rabbi Elazar talks about the secret meaning of the circumcision on the eighth day, the sign of the Holy Covenant, Yesod. The foreskin is said to be the impure serpent, that must be banished from Yisrael, and after it is removed it is placed in dust since God made the serpent live in the dust. Everyone must offer a son as a peace offering, and the reason for the circumcision on the eighth day is that at least one Shabbat must have passed.
