Leviticus 4
29 Ref And he is to put his hand on the head of the sin-offering and put it to death in the place where they put to death the burned offering.
30 Ref And the priest is to take some of the blood with his finger, and put it on the horns of the altar of burned offering, and all the rest of its blood is to be drained out at the base of the altar.
31 Ref And let all its fat be taken away, as the fat is taken away from the peace-offerings, and let it be burned on the altar by the priest for a sweet smell to the Lord; and the priest will take away his sin and he will have forgiveness.
