Leviticus 4:25-27

Living Bible

²⁵ Then the priest shall take some of the blood of this sin offering and place it with his finger upon the horns of the altar of burnt offerings, and the rest of the blood shall be poured out at the base of the altar. ²⁶ All the fat shall be burned upon the altar, just as if it were the fat of the sacrifice of a thank offering;^[a] thus the priest shall make atonement for the leader concerning his sin, and he shall be forgiven.

²⁷ “If any one of the common people sins and doesn’t realize it, he is guilty.
