Leviticus 4:19-21

New Century Version

¹⁹ He must remove all the fat from the animal and burn it on the altar; ²⁰ 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. ²¹ Then the priest must carry the bull outside the camp and burn it, just as he did with the first bull. This is the sin offering for the whole community.
