"And He said, Approach not hither, take the shoe from thy feet, for the place on which thou standest is a holy place; and upon it thou art to receive the Law, to teach it to the sons of Israel."
The Hebrew says only that the ground is holy. The Targum Pseudo-Jonathan on Exodus (3:5) tells us why. This is not merely the spot of a burning bush. This is the spot where, one day, the Torah itself will descend. The Holy One is announcing — at the first meeting, in the first sentence — that the same mountain now hosting the bush will later host Sinai.
This compresses forty years into a single verse. Everything that will happen — the ten plagues, the splitting of the sea, the manna, the water from the rock, the fire on the mountain — is already implicit in the ground under Moses's feet. God is not merely commissioning a liberator. He is commissioning a teacher. "Upon it thou art to receive the Law, to teach it to the sons of Israel."
This is the Jewish understanding of Moses in a sentence. He is not primarily a revolutionary. He is not primarily a lawgiver. He is rabbenu — our teacher. The exodus is a prerequisite to the classroom. You cannot teach a people inside chains; first you must unchain them. But the goal was never simply freedom. The goal was Torah.
And why remove the shoes? Because a teacher at holy ground should feel the earth beneath him — the thorns, the warmth, the dust. A prophet insulated from the ground he stands on will not teach Torah. He will only recite it.
Beloved, take off your shoes. Let the ground burn your soles a little. That is what teaching is for.
