1 Samuel 9:22-24

22Then Samuel took Saul and his young man and brought them into the hall and gave them a place at the head of those who had been invited, who were about thirty persons. 23And Samuel said to the cook, “Bring the portion I gave you, of which I said to you, ‘Put it aside.’” 24So the cook took up the leg and what was on it and set them before Saul. And Samuel said, “See, what was kept is set before you. Eat, because it was kept for you until the hour appointed, that you might eat with the guests.” So Saul ate with Samuel that day.
