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

27 "You shall consecrate the breast of the wave offering and the thigh of the heave offering which was waved and which was offered from the ram of ordination, from the one which was for Aaron and from the one which was for his sons.
