American Standard Version

²³ 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. ²⁴ 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.
