1 Samuel 10:18-22

and he said to the sons of Israel, “This is what the Lord, the God of Israel says: ‘I brought Israel up from Egypt, and I rescued you from the hand of the Egyptians and from the power of all the kingdoms that were oppressing you.’

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.”
