Leviticus 9:7-11

7Moses then said to Aaron, “Come near to the altar and 12offer your sin offering and your burnt offering, that you may make atonement for yourself and for the people; then make the offering 3for the people, that you may make atonement for them, just as the Lord has commanded.”

84So Aaron came near to the altar and slaughtered the calf of the sin offering which was for himself. 95Aaron’s sons presented the blood to him; and he dipped his finger in the blood and 6put 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 7lobe of the liver of the sin offering, he then offered up in smoke on the altar just as the Lord had commanded Moses. 118The flesh and the skin, however, he burned with fire outside the camp.
