Blood of Pesach & Circumcision

MISHNA: What are the differences between the Paschal lamb that the Jewish people offered in Egypt and the Paschal lamb offered in all later generations? The Paschal lamb the Jewish people offered in Egypt had to be taken from the tenth of the month of Nisan and required the people to sprinkle its blood with a bundle of hyssop, unlike the Paschal lamb in all later years, and its blood was also sprinkled upon the lintel and the two doorposts, and it was eaten with haste; in addition, the Paschal lamb in Egypt was only on one night, whereas the Paschal lamb throughout the generations is observed for seven days.

והיה לכם למשמרת AND IT SHALL BE IN YOUR KEEPING (or watching) — This expresses the idea of examining, and the text therefore implies that it requires examination against any blemish during the four days before slaughter (Pesachim 96a). And why did He order that it should be taken from the flock four days before its slaughter, something which He did not command in respect to the paschal-lamb that was offered by succeeding generations? Rabbi Mathia, the son of Cheresh, said, in answer: Behold, it says, (Ezekiel 16:8) “And I passed over thee (an allusion to God’s passing over the Israelites in Egypt) and looked upon thee, and behold, thy time was the time of love” — there had arrived the time to fulfil the oath which I had sworn to Abraham to redeem his children. They, however, possessed no mitzvot in which to engage in order that they should merit to be redeemed — as it is said (Ezekiel 16:7) “thou wast naked and bare” (i.e., bare of all merit earned through the fulfillment of the mitzvot). He therefore gave them two mitzvot: the blood of the paschal-lamb and the blood of the circumcision — for that night they circumcised themselves, as it is said (Ezekiel 16:6) “[When I passed over thee] I saw thee wallowing in thy bloods (בְּדָמַיִךְ is plural)” i.e., in two kinds of blood. Further it states, (Zechariah 9:11) “As for thee, also, because of the blood of the covenant I released thy prisoners out of the pit wherein there is no water”. And [also] because they were sunk in idolatry, He said unto them, (v. 21) משכו “Draw” — withdraw your hands from idols; וקחו לכם צאן “and take unto yourselves a lamb” to fulfill a mitzvah (Mekhilta d'Rabbi Yishmael 12:6).

The Sages taught: The verse states: “Justice, justice, shall you follow.” This teaches that one should follow the Sages to the academy where they are found. For example, follow after Rabbi Eliezer to Lod, after Rabban Yoḥanan ben Zakkai to Beror Ḥayil, after Rabbi Yehoshua to Peki’in, after Rabban Gamliel to Yavne, after Rabbi Akiva to Bnei Brak, after Rabbi Matya to Rome [Romi], after Rabbi Ḥananya ben Teradyon to Sikhnei, after Rabbi Yosei to Tzippori, after Rabbi Yehuda ben Beteira to Netzivin, after Rabbi Yehoshua to the exile [gola], i.e., Babylonia, after Rabbi Yehuda HaNasi to Beit She’arim, and after the Sages in the time of the Temple to the Chamber of Hewn Stone.
