Leviticus 7:30-32

his own hands shall bring the offerings of Jehovah made by fire; the fat with the breast shall he bring, that the breast may be waved for a wave-offering before Jehovah. And the priest shall burn the fat upon the altar; but the breast shall be Aaron’s and his sons’. And the right thigh shall ye give unto the priest for a heave-offering out of the sacrifices of your peace-offerings.
