Leviticus 4:26

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 .

He shall burn all the fat on the altar as he burned the fat of the fellowship offering. In this way the priest will make atonement for the leader`s sin, and he will be forgiven.

And he shall burn all his fat upon the altar, as the fat of the sacrifice of peace offerings : and the priest shall make an atonement for him as concerning his sin, and it shall be forgiven him.
