Leviticus 8:18-21

¹⁸Then he presented the ram of the burnt offering, and Aaron and his sons laid their hands on the head of the ram. ¹⁹Moses slaughtered it and sprinkled the blood around on the altar. ²⁰When he had cut the ram into its pieces, Moses offered up the head and the pieces and the suet in smoke. ²¹After he had washed the entrails and the legs with water, Moses offered 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.
