Exodus 34:5

The Lord descended in the cloud. — When Moses ceased to commune with God, the cloud removed from the door of the “Tent of Meeting,” and, as it would seem, disappeared. On Moses reaching the summit of Sinai it once more became visible, “descended” on the spot where Moses was, and “stood with him there.”

And proclaimed the name of the Lord. — Comp. Exodus 33:19; and for the terms of the proclamation see Exodus 34:6.
