1 Samuel 10:5-6

Afterward you will come to the hill of God where the Philistine garrison is; and it shall be as soon as you have come there to the city, that you will meet a group of prophets coming down from the high place with harp, tambourine, flute, and a lyre before them, and they will be prophesying. Then the Spirit of the LORD will come upon you mightily, and you shall prophesy with them and be changed into another man.
