Leviticus 9:23-24

²³And Moses goeth in — Aaron also — unto the tent of meeting, and they come out, and bless the people, and the honour of Jehovah appeareth unto all the people;

²⁴and fire cometh out from before Jehovah, and consumeth on the altar the burnt-offering, and the fat; and all the people see, and cry aloud, and fall on their faces.a
