1 Samuel 10:5-6

After that you will come to Gibeah, the hill of God, where an armed force of the Philistines is stationed: and when you come to the town, you will see a band of prophets coming down from the high place with instruments of music before them; and they will be acting like prophets: And the spirit of the Lord will come on you with power, and you will be acting like a prophet with them, and will be changed into another man.
