Leviticus 4:20, 26, 35

Thus shall he do with the bull. As he did with the bull of the sin offering, so shall he do with this. And the priest shall make atonement for them, and they shall be forgiven.

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

And all its fat he shall remove as the fat of the lamb is removed from the sacrifice of peace offerings, and the priest shall burn it on the altar, on top of the LORD’s food offerings. And the priest shall make atonement for him for the sin which he has committed, and he shall be forgiven.
