Leviticus 7:31-34

31 aThe priest shall burn the fat on the altar, but bthe breast shall be for Aaron and his sons. 32And cthe right thigh you shall give to the priest as a contribution from the sacrifice of your peace offerings. 33Whoever among the sons of Aaron offers the blood of the peace offerings and the fat shall have the right thigh for a portion. 34For the breast that is dwaved and the thigh that is econtributed I have taken from the people of Israel, out of the sacrifices of their peace offerings, and fhave given them to Aaron the priest and to his sons, as a perpetual due from the people of Israel.
