Leviticus 9:8

5 And they brought that which Moses commanded before the tabernacle of the congregation: and all the congregation drew near and stood before the LORD.

6 And Moses said, This is the thing which the LORD commanded that ye should do: and the glory of the LORD shall appear unto you.

7 And Moses said unto Aaron, Go unto the altar, and offer thy sin offering, and thy burnt offering, and make an atonement for thyself, and for the people: and offer the offering of the people, and make an atonement for them; as the LORD commanded.

8 Aaron therefore went unto the altar, and slew the calf of the sin offering, which was for himself.

9 And the sons of Aaron brought the blood unto him: and he dipped his finger in the blood, and put it upon the horns of the altar, and poured out the blood at the bottom of the altar:

10 But the fat, and the kidneys, and the caul above the liver of the sin offering, he burnt upon the altar; as the LORD commanded Moses.

11 And the flesh and the hide he burnt with fire without the camp.
