Exodus 19:20

And the Lord came down on Mount Sinai,.... In the above visible tokens of his presence and power; otherwise he is the incomprehensible Jehovah, that immense and omnipotent Being, who fills heaven and earth, and cannot be contained and circumscribed in either:

on the top of the mount; where the fire he descended in rested, and where the smoke and thick cloud were, as a token of his presence:

and the Lord called Moses up to the top of the mount; who either was at the bottom of it with the people, or in a higher ascent of it between God and them:

and Moses went up; to the top of it, where the Lord was, as he ordered him: a certain traveller y tells us that the top of this mount was scarce thirty feet in circumference.
