Leviticus 7:30-32

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

³¹And the priest shall make the fat smoke upon the altar; but the breast shall be Aaron's and his sons'.

³²And the right thigh shall ye give unto the priest for a heave-offering out of your sacrifices of peace-offerings.
