1SA 10:5

5 When you arrive at the hill [where people worship] God near Gibeah [town], where there is the camp where the Philistine soldiers stay, you will meet a group of prophets who will be coming down from the altar on top of the hill. There will be people in front of them who will be playing [various musical instruments]: a harp, a tambourine, a flute, and a lyre. And all of them will be speaking messages that come directly from God.
