Leviticus 4:8–10, 19, 26, 31
Then he shall remove all the fat from the bull of the sin offering—the fat that covers the entrails, all the fat that is on them, / both kidneys with the fat on them near the loins, and the lobe of the liver, which he is to remove with the kidneys— / just as the fat is removed from the ox of the peace offering. Then the priest shall burn them on the altar of burnt offering.
Leviticus 9:10
On the altar he burned the fat, the kidneys, and the lobe of the liver from the sin offering, as the LORD had commanded Moses.
