1 Samuel 19:23-24

19:23 So Saul went to Naioth in Ramah. The Spirit of God came upon him as well, and he walked along prophesying until he came to Naioth in Ramah. 19:24 He even stripped off his clothes and prophesied before Samuel. He lay there naked all that day and night. (For that reason it is asked, “Is Saul also among the prophets?”)
