Leviticus 4:35 in the King James Version
And he shall take away all the fat thereof, as the fat of the lamb is taken away from the sacrifice of the peace offerings; and the priest shall burn them upon the altar, according to the offerings made by fire unto the LORD: and the priest shall make an atonement for his sin that he hath committed, and it shall be forgiven him.

35 He shall remove all its fat, like the fat of the lamb is removed from the sacrifice of peace offerings. The priest shall burn them on the altar, on the offerings of the LORD made by fire. The priest shall make atonement for him concerning his sin that he has sinned, and he will be forgiven.
