Leviticus 7:33-34

33He among the sons of Aaron, who offers the blood of the peace offering and the fat, shall have the right thigh for his part.

34For the breast of the wave offering and the thigh of the heave offering I have taken from the children of Israel, from the sacrifices of their peace offerings, and I have given them to Aaron the priest and to his sons from the children of Israel by a statute forever.’ ”
