Lev Leviticus, chapter Book of Leviticus, chapter 4
And all the fat thereof shall he take off from it, and burn it upon the altar. Thus shall he do with the bullock; as he did with the bullock of the sin-offering, so shall he do with this; and the priest shall make atonement for them, and they shall be forgiven. Rom 3:25; Heb 10:4And he shall carry forth the bullock without the camp, and burn it as he burned the first bullock: it is the sin-offering for the assembly.
