Comentario sobre Exodo 33:21

הנה מקום אתי BEHOLD, THERE IS A PLACE BY ME — On the mountain where I am continually speaking with you there is a place prepared by Me for your sake where I will hide you that you may not be hurt by the vision. From there you will see what you will be permitted to see. A Midrashic explanation is that by the word מקום Scripture is speaking of the place where the Shechinah is and that He therefore said, “The place is by Me” and He did not say, “I am in the place”, because the Holy One, blessed be He, is the “place” of the Universe (comprises the Universe) but His Universe is not His place (does not encompass Him) (Genesis Rabbah 68:8).

BEHOLD, THERE IS A PLACE BY ME — on this mountain, where My Glory resides.

הנה מקום אתי, there does exist a place from which visions of G’d can be obtained, the place where both Moses and the prophet Elijah stood in a cave or beside a cave as described in Pessachim 54 as one the 10 items G’d created at dusk on the sixth day of creation.
