Leviticus 1:14-17

14“If your offering to the Lord is a bird, you must sacrifice a mourning dove or pigeon.

15The priest must bring it to the altar. He will break its neck and burn the bird on the altar. First, he will drain the blood against the side of the altar.

16Remove the gizzard with its filth and throw it on the east side of the altar on the place for the ashes.

17Then pull on the bird’s wings to tear the bird open, but don’t pull the wings off. Then the priest will lay the bird on the wood burning on the altar. It is a burnt offering, an offering by fire, a soothing aroma to the Lord.”
