1 Samuel 19:22-24

22Then Saul himself went to Ramah. He came to the large cistern at Secu and asked, “Where are Samuel and David?” “At Naioth in Ramah,” someone said.

23So he went to Naioth in Ramah. The Spirit of God also came on him, and as he walked along, he prophesied until he entered Naioth in Ramah.

24Saul then removed his clothes and also prophesied before Samuel; he collapsed and lay naked all that day and all that night. That is why they say, “Is Saul also among the prophets?”
