Leviticus 9:8-11

81So Aaron came near to the altar and slaughtered the calf of the sin offering which was for himself. 92Aaron’s sons then presented the blood to him; and he dipped his finger in the blood and 3put some on the horns of the altar, and poured out the rest of the blood at the base of the altar. 10The fat and the kidneys and the 4lobe of the liver of the sin offering he then offered up in smoke on the altar, just as the Lord had commanded Moses. 115The flesh and the hide, however, he burned with fire outside the camp.
