The Talmudic sage known simply as Rebbi — Rabbi Yehuda HaNasi, the compiler of the Mishnah (the earliest code of rabbinic law) — raised a striking question about the greatness of Moses. Would we only need to acknowledge Moses's extraordinary status if we assumed that the Holy One, Blessed be He, had actually retracted a divine directive given to him?
Rebbi's answer cuts to the heart of how God communicates with prophets. The apparent contradiction in God's instructions was not a reversal at all. Rather, God spoke the way He did because a person is naturally prompted to greater zeal — greater urgency and devotion — at two critical moments: at the time of learning what must be done, and at the time of actually doing it.
This teaching from the Mekhilta reveals something profound about divine pedagogy. When God gave Moses instructions that seemed to shift or intensify, it was not because God changed His mind. It was a deliberate strategy to kindle enthusiasm in Moses at precisely the moments when motivation matters most. The moment you hear a command and the moment you carry it out are the two windows when the human spirit is most receptive to passion and commitment.
Moses's greatness, then, does not depend on God reversing Himself. Moses was great because he responded to every divine instruction with fresh zeal, treating each moment of revelation as if hearing God's voice for the very first time.
