Leviticus 8:18-21

18Then Moses presented the ram for the burnt offering, and Aaron and his sons laid their hands on its head. 19Moses slaughtered the ram and splattered the blood on all sides of the altar. 20He cut the ram into pieces and burned the head, the pieces, and the fat. 21He washed the entrails and legs with water and burned the entire ram on the altar as a burnt offering, a pleasing aroma, a food offering to the LORD, just as the LORD had commanded Moses.
