Exodus 29:19-22

19“Take the other ram, and Aaron and his sons shall lay their hands on its head. 20Slaughter it, take some of its blood and put it on the lobes of the right ears of Aaron and his sons, on the thumbs of their right hands, and on the big toes of their right feet. Then splash blood against the sides of the altar.

21And take some blood from the altar and some of the anointing oil and sprinkle it on Aaron and his garments and on his sons and their garments. Then he and his sons and their garments will be consecrated. 22“Take from this ram the fat, the fat tail, the fat on the internal organs, the long lobe of the liver, both kidneys with the fat on them, and the right thigh. (This is the ram for the ordination.)
