Leviticus 8:16-18

¹⁶Moses took all the fat that covers the insides, the best part of the liver, both kidneys with the fat on them, burned all of it on the altar.

¹⁷But the rest of the bull—the skin, the meat, and the waste he burned outside the camp, as the Lord had ordered him to do.

¹⁸Moses brought the ram for the burnt offering, and Aaron and his sons put their hands on its head.
