Leviticus 7:30-32

³⁰His own hands shall bring the offerings of the LORD made by fire, the fat with the breast, it shall he bring, that the breast may be waved for a wave offering before the LORD.

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

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