Leviticus 7:31-33

King James Version

³¹ And the priest shall burn the fat upon the altar: but the breast shall be Aaron's and his sons'.

³² And the right shoulder shall ye give unto the priest for an heave offering of the sacrifices of your peace offerings.

³³ He among the sons of Aaron, that offereth the blood of the peace offerings, and the fat, shall have the right shoulder for his part.
