1 Samuel 19:23; 1 Samuel 19:24

23 As he was going there, the spirit of God took control of him also, and he danced and shouted all the way to Naioth.

24 He took off his clothes and danced and shouted in Samuel's presence, and lay naked all that day and all that night. (This is how the saying originated, "Has even Saul become a prophet?")
