Exodus 29:22; Exodus 29:27

22 "You shall also take the fat from the ram and the fat tail and the fat that covers the entrails, and the long lobe of the liver and the two kidneys with the fat that is on them, and the right thigh (for it is a ram of ordination),

27 And you shall consecrate the breast of the wave offering that is waved and the thigh of the priests' portion that is contributed from the ram of ordination, from what was Aaron's and his sons'.
