Leviticus 4:30-35

30Then the priest shall take some of its blood with his finger, put it on the horns of the altar of burnt offering, and pour all the remaining blood at the base of the altar.

31He shall remove all its fat, as fat is removed from the sacrifice of the peace offering; and the priest shall burn it on the altar for a sweet aroma to the Lord. So the priest shall make atonement for him, and it shall be forgiven him.

32‘If he brings a lamb as his sin offering, he shall bring a female without blemish.

33Then he shall lay his hand on the head of the sin offering, and kill it as a sin offering at the place where they kill the burnt offering.

34The priest shall take some of the blood of the sin offering with his finger, put it on the horns of the altar of burnt offering, and pour all the remaining blood at the base of the altar.

35He shall remove all its fat, as the fat of the lamb is removed from the sacrifice of the peace offering. Then the priest shall burn it on the altar, according to the offerings made by fire to the Lord. So the priest shall make atonement for his sin that he has committed, and it shall be forgiven him.
