1 Samuel 10:19-22
English Standard Version
20Then Samuel brought all the tribes of Israel near, and the tribe of Benjamin was taken by lot.
21He brought the tribe of Benjamin near by its clans, and the clan of the Matrites was taken by lot; and Saul the son of Kish was taken by lot. But when they sought him, he could not be found.
22So they inquired again of the Lord, "Is there a man still to come?" and the Lord said, "Behold, he has hidden himself among the baggage."
