Leviticus 4:25-27

²⁵Then the priest must put some of the animal's blood into a bowl and dip one of his fingers in it and put some of the blood on the corners of the projections of the altar. Then he must pour out the rest of the blood at the base of the altar.

²⁶Then he must burn all the fat on the altar, as was done with the fat of the offering to maintain good fellowship with Yahweh. As a result of the priest's doing that, the leader will no longer be guilty for his sin and he will be forgiven.

²⁷If one of the Israeli people who is not a priest sins without intending to sin, and does something that is forbidden in any of the commands of Yahweh his God, he will be guilty.
