Leviticus 8:18-24

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. 22He then presented the other ram, the ram for the ordination, and Aaron and his sons laid their hands on its head. 23Moses slaughtered the ram and took some of its blood and put it on the lobe of Aaron’s right ear, on the thumb of his right hand and on the big toe of his right foot. 24Moses also brought Aaron’s sons forward and put some of the blood on the lobes of their right ears, on the thumbs of their right hands and on the big toes of their right feet. Then he splashed blood against the sides of the altar.
