Leviticus 8:14-17

Moses brought out the bull for the Absolution-Offering. Aaron and his sons placed their hands on its head. Moses slaughtered the bull and purified the Altar by smearing the blood on each of the horns of the Altar with his finger. He poured out the rest of the blood at the base of the Altar. He consecrated it so atonement could be made on it. Moses took all the fat on the entrails and the lobe of liver and the two kidneys with their fat and burned it all on the Altar. The bull with its hide and meat and guts he burned outside the camp, just as GOD had commanded Moses.
