Leviticus 9:9-11

American Standard Version

⁹ And the sons of Aaron presented 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 base of the altar: ¹⁰ but the fat, and the kidneys, and the caul from the liver of the sin-offering, he burnt upon the altar; as Jehovah commanded Moses. ¹¹ And the flesh and the skin he burnt with fire without the camp.
