1 Samuel 19:22-24

22Then Saul went to Ramah himself and came to the great well that is in Secu; and he asked, “Where are Samuel and David?” And he was told, “They are at Naioth [with the prophets] in Ramah.”

23So he went on to Naioth in Ramah; and the Spirit of God came upon him too, and he went along continually prophesying until he came to Naioth in Ramah.

24He also took off his [royal] robes [and armor] and prophesied before Samuel and lay down naked all that day and night. So they say, “Is Saul also among the prophets?”
