1 Samuel 9:22-24

22And Samuel took Saul and his servant, and brought them into the chamber, and gave them a place at the head of them that were invited; and they were about thirty persons.

23And Samuel said to the cook, Bring the portion that I gave thee, of which I said to thee, Set it by thee.

24And the cook took up the shoulder, and what was on it, and set [it] before Saul. And he said, Behold that which has been reserved! set it before thee, eat; for against the set time has it been kept for thee, since I said, I will invite the people. So Saul ate with Samuel that day.
