Our Rabbis said: Moses did three things in which his judgment was [later] confirmed by the judgment of the Omnipresent. At Mount Sinai he expounded, saying: If Israel, who have not been designated [to hear divine] speech, He [nevertheless] said to them: “Do not come near a woman” (Exodus 19:15), I, who is designated [to hear divine] speech, is it not logical that I separate myself from woman? The Holy One blessed be He agreed with him, as it is stated: “But you, stand here with Me” (Deuteronomy 5:28).
The second he expounded in the Tent of Meeting, saying: If at Sinai, whose sanctity was limited only to the revelation at Sinai, I ascended only with permission, as it is stated: “The Lord called to him from the mountain saying” (Exodus 19:3), then how can I enter the Tent of Meeting, which is for the generations, unless the Holy One blessed be He summons me? He agreed with his judgment, as it is stated: “The Lord called to Moses, and spoke to him from the Tent of Meeting” (Leviticus 1:1).
The third he expounded regarding the statute of the paschal offering: When Israel made the calf, he said: If, regarding the paschal offering, which was a one-time observance in Egypt, He said to me: “This is the statute of the paschal offering: no foreigner shall [eat of it],” Israel, who worshipped idols [with the Golden Calf], can they receive the Torah? Immediately, “He broke them [the tablets] at the foot of the mountain” (Exodus 32:19).
