Leviticus 9:22-24

And Aaron lifted up his hands toward the people, and blessed them; and he came down from offering the sin-offering, and the burnt-offering, and the peace-offerings. And Moses and Aaron went into the tent of meeting, and came out, and blessed the people: and the glory of Jehovah appeared unto all the people. And there came forth fire from before Jehovah, and consumed upon the altar the burnt-offering and the fat: and when all the people saw it, they shouted, and fell on their faces.
