Leviticus 4:20
And he shall do with the bullock as he did with the bullock for a sin offering, so shall he do with this: and the priest shall make an atonement for them, and it shall be forgiven them. And he shall do with the bullock as he did with the bullock for a sin offering, so shall he do with this: and the priest shall make an atonement for them, and it shall be forgiven them.
Leviticus 4:20 sets forth the procedure for the sin offering when the sin is that of the anointed priest or that of the whole congregation. In that case the blood of the bullock is carried into the holy place, where it is sprinkled before the veil of the sanctuary and placed upon the horns of the golden altar of incense. The fat of the offering is then separated and consumed by fire upon the altar of burnt offering in the court. The remainder of the body of the victim is not eaten but is carried forth and burned without the camp.
