1 Samuel 10:5-6

After that you will come to the hill of God where the garrison of the Philistines is; and when you come there to the city, you will meet a group of prophets coming down from the high place [of worship] with harp, tambourine, flute, and lyre before them, and they will be prophesying. Then the Spirit of the LORD will come upon you mightily, and you will prophesy with them, and you will be changed into another man.
