Leviticus 9:8-11 - The Sin Offering For The Priests
8 And Aaron shall draw near to the altar and slaughter the calf for sin, which is to him. 9 And Aaron's sons will bring the blood to him, and he will dip his finger in the blood, and give upon the horns of the altar, and he will pour out the blood at the foundation of the altar. 10 And the fat, and the kidneys, and the lobe from the liver, from the sin, he burnt upon the altar; as Jehovah commanded Moses. 11 And the flesh and the skin he burnt in fire without the camp.
