Leviticus 1:14-17

14“ ‘If the offering to the Lord is a burnt offering of birds, you are to offer a dove or a young pigeon.

15The priest shall bring it to the altar, wring off the head and burn it on the altar; its blood shall be drained out on the side of the altar.

16He is to remove the crop and the feathers and throw them down east of the altar where the ashes are.

17He shall tear it open by the wings, not dividing it completely, and then the priest shall burn it on the wood that is burning on the altar. It is a burnt offering, a food offering, an aroma pleasing to the Lord.
