Leviticus 4:20, 26, 35

he will do the same thing with this bull that he did with the first bull of the sin offering. In this way the priest removes the sins of the people so they will belong to the LORD and be forgiven.

He must burn all the goat’s fat on the altar in the same way he burns the fat of the fellowship offerings. In this way the priest removes the ruler’s sin so he belongs to the LORD, and the LORD will forgive him.

Then the priest must remove all the lamb’s fat in the same way that the lamb’s fat is removed from the fellowship offerings. He must burn the pieces on the altar on top of the offerings made by fire for the LORD. In this way the priest will remove that person’s sins so he will belong to the LORD, and the LORD will forgive him.
