Leviticus

And if the burnt sacrifice for his offering to the Lord be of fowls, then he shall bring his offering of turtledoves, or of young pigeons.

And he shall cleave it with the wings thereof, but shall not divide it asunder: and the priest shall burn it upon the altar, upon the wood that is upon the fire: it is a burnt sacrifice, an offering made by fire, of a sweet savour unto the Lord.

And almost all things are by the law purged with blood; and without shedding of blood is no remission.

And he shall burn all his fat upon the altar, as the fat of the sacrifice of peace offerings: and the priest shall make an atonement for him as concerning his sin, and it shall be forgiven him.

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.
