Lev Leviticus, chapter Book of Leviticus, chapter 4
And he shall take all his fat from him, and burn [it] upon the altar.
And he shall do with the bullock as he did with the bullock for a sin offering, so shall he do with this: and the priest shall make an atonement for them, and it shall be forgiven them.Rom 3:25; Heb 10:4
And he shall carry forth the bullock without the camp, and burn him as he burned the first bullock: it [is] a sin offering for the congregation.
