Leviticus 1:12-16

He shall then cut it into its pieces with its head and its suet, and the priest shall arrange them on the wood which is on the fire that is on the altar.

The entrails, however, and the legs he shall wash with water. And the priest shall offer all of it, and offer it up in smoke on the altar; it is a burnt offering, an offering by fire of a soothing aroma to the Lord.

‘But if his offering to the Lord is a burnt offering of birds, then he shall bring his offering from the turtledoves or from young doves.

The priest shall bring it to the altar, and pinch off its head, and offer it up in smoke on the altar; and its blood is to be drained out on the side of the altar.

He shall also remove its craw with its feathers and throw it beside the altar eastward, to the place of the fatty ashes.
