1 Samuel 10:5-6

5After that you shall come to Gibeath-elohim, where there is a garrison of the Philistines. And there, as soon as you come to the city, you will meet a group of prophets coming down from the high place with harp, tambourine, flute, and lyre before them, prophesying.

6Then the Spirit of the Lord will rush upon you, and you will prophesy with them and be turned into another man.
