I Samuel 10:11

11 Now when Saul's old friends saw him among the band of prophets, the people said to one another, What has come to Saul, the son of Kish? Is even Saul among the prophets?

11 When all those who had formerly known him saw him prophesying with the prophets, they asked each other, "What is this that has happened to the son of Kish? Is Saul also among the prophets?"
