Then the cook lifted up the leg (thigh) with the meat that was on it [indicating that it was the priest’s honored portion] and placed it before Saul. Samuel said, “Here is what has been reserved [for you]. Set it before you and eat, because it has been kept for you until the appointed time, ever since I invited the people.” So Saul ate with Samuel that day.

For the breast which is waved and the right leg which is lifted up on high I have taken from the children of Israel, from their peace-offerings, and have given them to Aaron the priest and to his sons as their right for ever from the children of Israel.
