Leviticus 9:18-20

New International Version

¹⁸ He slaughtered the ox and the ram as the fellowship offering for the people.^(A) His sons handed him the blood, and he splashed it against the sides of the altar. ¹⁹ But the fat portions of the ox and the ram—the fat tail, the layer of fat, the kidneys and the long lobe of the liver— ²⁰ these they laid on the breasts, and then Aaron burned the fat on the altar.
