Leviticus 7:1-5

“ ‘These are the teachings about the penalty offering, which is most holy: The penalty offering must be killed where the whole burnt offering is killed. Then the priest must sprinkle its blood on all sides of the altar. He must offer all the fat from the penalty offering—the fat tail, the fat that covers the inner organs, both kidneys with the fat that is on them near the lower back muscle, and the best part of the liver, which is to be removed with the kidneys. The priest must burn all these things on the altar as an offering made by fire to the LORD. It is a penalty offering.
