Leviticus 9:22-24

22Aaron lifted up his hands toward the people and blessed them. And having made the sin offering, the burnt offering, and the peace offering, he stepped down.

23Moses and Aaron then entered the Tent of Meeting. When they came out, they blessed the people, and the glory of the LORD appeared to all the people. 24Fire came out from the presence of the LORD and consumed the burnt offering and the fat portions on the altar. And when all the people saw it, they shouted for joy and fell facedown.
