So the cook picked up the leg and what was attached to it and set it before Saul. Then Samuel said, "Here is what was kept back. It was set apart for you. Eat, for it has been kept for you for this occasion, from the time I said, 'I have invited the people.'" So Saul dined with Samuel that day.

And their meat belongs to you, just as the breast and right thigh of the wave offering belong to you.

1 Samuel 9:23
And Samuel said to the cook, "Bring the portion I gave you and told you to set aside."

And the cook took up the shoulder, and that which was on it, and set it before Saul. And Samuel said, Behold that which is left! set it before you, and eat: for to this time has it been kept for you since I said, I have invited the people. So Saul did eat with Samuel that day.
