Leviticus 7:32-34

32The right thigh you must give as a contribution offering to the priest from your peace offering sacrifices.

33The one from Aaron’s sons who presents the blood of the peace offering and fat will have the right thigh as his share,

34for 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.’”
