Leviticus 7:32-34

32And you shall give 1the right thigh to the priest as a 2contribution from the sacrifices of your peace offerings. 33The one among the sons of Aaron who offers the blood of the peace offerings and the fat, the right thigh shall be his as his portion. 34For I have taken from the sons of Israel 3the breast of the wave offering and the thigh of the 4contribution from the sacrifices of their peace offerings, and have given them to Aaron the priest and to his sons as their allotted portion forever from the sons of Israel.
