1 Samuel 10:9-16

Then it happened when Saul turned his back to leave Samuel, God changed his heart; and all those signs came to pass that day. When they came to the hill [Gibeah], behold, a group of prophets met him; and the Spirit of God came on him mightily, and he prophesied [under divine guidance] among them. Now when all who knew Saul previously saw that he actually prophesied now [by inspiration] with the prophets, the people said one to another, “What has happened to [Saul, who is nobody but] the son of Kish? Is Saul also among the prophets?” And a man from there answered, “But who is the father of the others?” So it became a proverb, “Is Saul also among the prophets?” When Saul had finished prophesying, he went to the high place [of worship]. Saul’s uncle said to him and to his servant, “Where did you go?” And Saul said, “To look for the donkeys. And when we saw that they were nowhere to be found, we went to Samuel [for help].” Saul’s uncle said, “Please tell me, what did Samuel say to you?” And 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.
