Context Reading
32“‘If he brings a lamb as his offering for a sin offering, he shall bring a female without defect. 33He shall lay his hand on the head of the sin offering, and kill it for a sin offering in the place where they kill the burnt offering. 34The priest shall take some of the blood of the sin offering with his finger, and put it on the horns of the altar of burnt offering; and all the rest of its blood he shall pour out at the base of the altar. 35He shall remove all its fat, like the fat of the lamb is removed from the sacrifice of peace offerings. The priest shall burn them on the altar, on the offerings of Yahweh made by fire. The priest shall make atonement for him concerning his sin that he has sinned, and he will be forgiven.
