1 Samuel 10:9-16

Then it happened when he turned his back to leave Samuel, God changed his heart; and all those signs came about on that day. When they came to the hill there, behold, a group of prophets met him; and the Spirit of God came upon him mightily, so that he prophesied among them. It came about, when all who knew him previously saw that he prophesied now with the prophets, that the people said to one another, “What has happened to the son of Kish? Is Saul also among the prophets?” A man there said, “Now, who is their father?” Therefore it became a proverb: “Is Saul also among the prophets?” When he had finished prophesying, he came to the high place. Now Saul’s uncle said to him and his servant, “Where did you go?” And he said, “To look for the donkeys. When we saw that they could not be found, we went to Samuel.” Saul’s uncle said, “Please tell me what Samuel said to you.” So Saul said to his uncle, “He told us plainly that the donkeys had been found.” But he did not tell him about the matter of the kingdom which Samuel had mentioned.
