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

He shall take from it all the fat of the bull as the sin offering. The fat that covers the entrails and all the fat which is on the entrails, the two kidneys and the fat that is on them by the flanks, and the fatty lobe attached to the liver above the kidneys, he shall remove, as it was taken from the bull of the sacrifice of the peace offering; and the priest shall burn them on the altar of the burnt offering.

And he shall burn all its fat on the altar, like the fat of the sacrifice of the peace offering. So the priest shall make atonement for him concerning his sin, and it shall be forgiven him.

He shall remove all its fat, as fat is removed from the sacrifice of the peace offering; and the priest shall burn it on the altar for a sweet aroma to the LORD. So the priest shall make atonement for him, and it shall be forgiven him.

He shall remove all its fat, as the fat of the lamb is removed from the sacrifice of the peace offering. Then the priest shall burn it on the altar, according to the offerings made by fire to the LORD. So the priest shall make atonement for his sin that he has committed, and it shall be forgiven him.
