Leviticus 7:29-32

²⁹Speak unto the children of Israel, saying, He that offereth the sacrifice of his peace offerings unto the LORD shall bring his oblation unto the LORD of the sacrifice of his peace offerings.

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.
