1 Samuel 19:22-24

22Then he also went to Ramah, and came to the great well that is at Sechu. So he asked, and said, “Where are Samuel and David?” And someone said, “Indeed they are at Naioth in Ramah.”

23So he went there to Naioth in Ramah. Then the Spirit of God was upon him also, and he went on and prophesied until he came to Naioth in Ramah.

24And he also stripped off his clothes and prophesied before Samuel in like manner, and lay down naked all that day and all that night. Therefore they say, “Is Saul also among the prophets?”
