Leviticus 8:18-21

18He then presented the ram for the burnt offering, and Aaron and his sons laid their hands on its head. 19Then Moses slaughtered the ram and splashed the blood against the sides of the altar. 20He cut the ram into pieces and burned the head, the pieces and the fat. 21He washed the internal organs and the legs with water and burned the whole ram on the altar. It was a burnt offering, a pleasing aroma, a food offering presented to the Lord, as the Lord commanded Moses.
