Leviticus 8:18-21

18Then he presented 1the ram of the burnt offering, and Aaron and his sons laid their hands on the head of the ram. 192Moses slaughtered it and sprinkled the blood around on the altar. 20When he had cut the ram into its pieces, Moses 3offered up the head and the pieces and the suet in smoke. 21After he had washed the entrails and the legs with water, Moses 4offered up the whole ram in smoke on the altar. It was a burnt offering for a soothing aroma; it was an offering by fire to the Lord, just as the Lord had commanded Moses.
