Leviticus 8:16-20

He also took all the fat that was on the entrails and the lobe of the liver, and the two kidneys and their fat; and Moses offered it up in smoke on the altar.

But the bull and its hide, its flesh, and its refuse he burned in the fire outside the camp, just as the Lord had commanded Moses.

Then he presented the ram of the burnt offering, and Aaron and his sons laid their hands on the head of the ram.

And Moses slaughtered it and sprinkled the blood around on the altar.

When he had cut the ram into its pieces, Moses offered up the head and the pieces and the suet in smoke.
