Leviticus 4:8-10, 26, 31, 35

Then the priest must remove all the fat of the bull to be offered as a sin offering. This includes all the fat around the internal organs, the two kidneys and the fat around them near the loins, and the long lobe of the liver. He must remove these along with the kidneys, just as he does with cattle offered as a peace offering, and burn them on the altar of burnt offerings.

Then he must burn all the goat’s fat on the altar, just as he does with the peace offering. Through this process, the priest will purify the leader from his sin, making him right with the LORD, and he will be forgiven.

Then he must remove all the goat’s fat, just as he does with the fat of the peace offering. He will burn the fat on the altar, and it will be a pleasing aroma to the LORD. Through this process, the priest will purify the people, making them right with the LORD, and they will be forgiven.

Then he must remove all the sheep’s fat, just as he does with the fat of a sheep presented as a peace offering. He will burn the fat on the altar on top of the special gifts presented to the LORD. Through this process, the priest will purify the people from their sin, making them right with the LORD, and they will be forgiven.
