1 Samuel 10:9-13

9When Saul turned to leave Samuel, God changed his heart, and all the signs came about that day.

10When Saul and his servant arrived at Gibeah, a group of prophets met him. Then the Spirit of God came powerfully on him, and he prophesied along with them.

11Everyone who knew him previously and saw him prophesy with the prophets asked each other, “What has happened to the son of Kish? Is Saul also among the prophets?”

12Then a man who was from there asked, “And who is their father?” As a result, “Is Saul also among the prophets?” became a popular saying.

13Then Saul finished prophesying and went to the high place.
