Leviticus 7:28-38

And Jehovah spake unto Moses, saying, Speak unto the children of Israel, saying, He that offereth the sacrifice of his peace-offerings unto Jehovah shall bring his oblation unto Jehovah out of the sacrifice of his peace-offerings: 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. He among the sons of Aaron that offereth the blood of the peace-offerings, and the fat, shall have the right thigh for a portion. For the wave-breast and the heave-thigh have I taken of the children of Israel out of the sacrifices of their peace-offerings, and have given them unto Aaron the priest and unto his sons as their portion for ever from the children of Israel. This is the anointing-portion of Aaron, and the anointing-portion of his sons, out of the offerings of Jehovah made by fire, in the day when he presented them to minister unto Jehovah in the priest’s office; which Jehovah commanded to be given them of the children of Israel, in the day that he anointed them. It is their portion for ever throughout their generations. This is the law of the burnt-offering, of the meal-offering, and of the sin-offering, and of the trespass-offering, and of the consecration, and of the sacrifice of peace-offerings; which Jehovah commanded Moses in mount Sinai, in the day that he commanded the children of Israel to offer their oblations unto Jehovah, in the wilderness of Sinai.
