1 Samuel 10:11-12

10:11 When everyone who had known him previously saw him prophesying with the prophets, the people all asked one another, “What on earth has happened to the son of Kish? Does even Saul belong with the prophets?”

10:12 A man who was from there replied, “And who is their father?” Therefore this became a proverb: “Is even Saul among the prophets?”
