Leviticus 4:20, 31

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.

Then the priest must remove all the goat’s fat in the same way the fat is removed from the fellowship offerings. He must burn it on the altar as a smell pleasing to the LORD. In this way the priest will remove that person’s sin so he will belong to the LORD, and the LORD will forgive him.
