Moses and Aaron went from the presence of the assembly to the entrance of the Tent of Meeting and fell on their faces, and the glory of Yahweh appeared to them. Bible

“the glory of Yahweh appeared.” In this context, “the glory of Yahweh” was the glorious light that surrounded Yahweh. When the glory of Yahweh appeared, then Yahweh Himself was there. [For more on the glory of God, see commentary on Ezekiel 1:28].
