Exodus 33:21 - Joseph Benson’s Commentary on the Old and New Testaments

Behold, there is a place by me Probably meant of some part of mount Horeb, where Moses had long enjoyed intercourse with God, and from which the tabernacle, where the cloud of glory now appeared, was at no great distance. And thou shalt stand upon a rock If not that from which the water was miraculously brought, yet certainly one which, like it, was emblematical of Christ, (1 Corinthians 10:4,) through whom alone we can have the knowledge of the glory of God. For this glory none can see to their comfort but those that believe, confide, and take shelter in him. While my glory passeth by, I will put thee in a cleft of the rock As the rock might limit Moses's view of the divine glory, that he might not be overwhelmed by it; so the refulgent rays of the glory of God are limited and concealed by the humanity of Christ, and by faith we are hid in him, and secured from the effects of the glorious justice and wrath of God, which would otherwise consume us. I will cover thee with my hand while I pass by My invisible power shall spread a cloud before thee, that thou mayest not be overpowered and struck dead by the excessive glory, and so be undone by thy own desires.
