1 Samuel 10:9-13

Then it happened, when he turned his back to leave Samuel, that God changed his heart; and all those signs came about on that day.

When they came there to the hill, behold, a group of prophets met him; and the Spirit of God rushed upon him, so that he prophesied among them.

And 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? Is Saul also among the prophets?”

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

When he had finished prophesying, he came to the high place.
