Leviticus 9:23-24

9:23 Moses and Aaron then entered into the Meeting Tent. When they came out, they blessed the people, and the glory of the Lord appeared to all the people. 9:24 Then fire went out from the presence of the Lord and consumed the burnt offering and the fat parts on the altar, and all the people saw it, so they shouted loudly and fell down with their faces to the ground.
