Leviticus 1:7-9

King James Version

⁷ And the sons of Aaron the priest shall put fire upon the altar, and lay the wood in order upon the fire:

⁸ And the priests, Aaron's sons, shall lay the parts, the head, and the fat, in order upon the wood that is on the fire which is upon the altar:

⁹ But his inwards and his legs shall he wash in water: and the priest shall burn all on the altar, to be a burnt sacrifice, an offering made by fire, of a sweet savour unto the Lord.
