1 Samuel 10:19-23

But today you have rejected your God, who saves you from all your catastrophes and your distresses; yet you have said, ‘No, but put a king over us!’ Now then, present yourselves before the Lord by your tribes and by your groups of thousands.”

So Samuel brought all the tribes of Israel forward; and the tribe of Benjamin was selected by lot.

Then he brought the tribe of Benjamin forward by its families, and the Matrite family was selected by lot. And Saul the son of Kish was selected by lot; but when they looked for him, he could not be found.

Therefore they inquired further of the Lord: “Has the man come here yet?” And the Lord said, “Behold, he is hiding himself among the baggage.”

So they ran and took him from there, and when he stood among the people, he was taller than any of the people from his shoulders upward.
