1 Samuel 10:11-12

11And it came about, when all who previously knew him saw that he was indeed prophesying with the prophets, that the people said to one another, “What is this that has happened to the son of Kish? 1Is Saul also among the prophets?”

12And a man from there responded and said, “And who is their father?” Therefore it became a saying: “2Is Saul also among the prophets?”
