Rabbi Shimon tells Moses that it is through Moses' deeds that the Shechinah is renewed in the prayers of the patriarchs. He goes on to speak about the renewal that takes place during the prayers of the Festival of Weeks. His exposition includes a discussion of the numerical value of "all" (Heb. kol), the sea of the Torah, and Malchut that is the end of all the seas. The numbers seven and fifty are emphasized.
