Leviticus 9:22-24

Then Aaron lifted his hand toward the people, blessed them, and came down from offering the sin offering, the burnt offering, and peace offerings. And Moses and Aaron went into the tabernacle of meeting, and came out and blessed the people. Then the glory of the LORD appeared to all the people, and fire came out from before the LORD and consumed the burnt offering and the fat on the altar. When all the people saw it, they shouted and fell on their faces.
