Leviticus 1:16-17

16He shall also remove its craw with its feathers and throw it beside the altar eastward, to the place of the 1fatty ashes.

17Then he shall tear it by its wings, but 2shall not sever it. And the priest shall offer it up in smoke on the altar, on the wood which is on the fire; 3it is a burnt offering, an offering by fire of a soothing aroma to the Lord.
