1 Samuel 10:5-6

5After that, you will arrive at the hill of God, where the garrison of the Philistines is. It will come about, as soon as you enter the town, that you will meet a band of prophets coming down from the high place, preceded by a harp, a tambourine and a flute, and they will be prophesying.

6Then the Ruach of Adonai will seize you and you will prophesy with them—you will turn into another man.
