I Samuel 10:20-22

And when Samuel had caused all the tribes of Israel to come near, the tribe of Benjamin was chosen. When he had caused the tribe of Benjamin to come near by their families, the family of Matri was chosen. And Saul the son of Kish was chosen. But when they sought him, he could not be found. Therefore they inquired of the LORD further, “Has the man come here yet?” And the LORD answered, “There he is, hidden among the equipment.”
