'Band Of Prophets' in the Bible

After that, shalt thou come unto the hill of God, where is the garrison of the Philistines, - and it shall be, as thou comest in thither into the city, thou shalt light upon a band of prophets, coming down from the high place, and, before them, a harp, and a timbrel, and a flute, and a lyre, they having been moved to prophesy.

And, when they came thither to the hill, lo! a band of prophets coming to meet him, - then came suddenly upon him, the Spirit of God, and he was moved to prophesy in their midst.
