Leviticus 1
14 Ref 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.
15 Ref And the priest shall bring it unto the altar, and wring off his head, and burn it on the altar; and the blood thereof shall be wrung out at the side of the altar:
16 Ref And he shall pluck away his crop with his feathers, and cast it beside the altar on the east part, by the place of the ashes:
17 Ref 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 savor unto the LORD.
