Leviticus 4:29-32

²⁹And he shall lay his hand upon the head of the sin-offering, and kill the sin-offering in the place of burnt-offering.

³⁰And the priest shall take of the blood thereof with his finger, and put it upon the horns of the altar of burnt-offering, and all the remaining blood thereof shall he pour out at the base of the altar.

³¹And all the fat thereof shall he take away, as the fat is taken away from off the sacrifice of peace-offerings; and the priest shall make it smoke upon the altar for a sweet savour unto the LORD; and the priest shall make atonement for him, and he shall be forgiven.

³²And if he bring a lamb as his offering for a sin-offering, he shall bring it a female without blemish.
