Leviticus 7:32-34

7:32 The right thigh you must give as a contribution offering to the priest from your peace offering sacrifices. 7:33 The one from Aaron’s sons who presents the blood of the peace offering and fat will have the right thigh as his share, 7:34 for the breast of the wave offering and the thigh of the contribution offering I have taken from the Israelites out of their peace offering sacrifices and have given them to Aaron the priest and to his sons from the people of Israel as a perpetual allotted portion.’”
