Leviticus 9:22-24

Then Aaron lifted his hands toward the people and blessed them, and came down [from the altar of burnt offering] after presenting the sin offering, the burnt offering, and the peace offerings. Moses and Aaron went into the Tent of Meeting, and when they came out they blessed the people, and the glory and brilliance of the LORD [the Shekinah cloud] appeared to all the people [as promised]. [Lev 9:6] Then fire came out from before the LORD and consumed the burnt offering and the portions of fat on the altar; and when all the people saw it, they shouted and fell face downward [in awe and worship].
