1 Samuel 19:23-24
23 So Saul went to Naioth at Ramah. But the Spirit of God came even upon him, and he walked along prophesying until he came to Naioth.
24 He stripped off his robes and also prophesied in Samuel’s presence. He lay that way all that day and night. This is why people say, “Is Saul also among the prophets?”
