I Samuel 10:5-6

⁵Afterward 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. ⁶Then the Spirit of the Lord will come upon you mightily, and you shall prophesy with them and be changed into another man.
