1SA 10:5

5 After these things thou shalt come into the hill of the Lord, where is the standing place, that is, the forcelet, of Philistines; and when thou shalt enter into the city, there thou shalt have meeting thee a flock, or a company, of prophets, coming down from the high place, and a psaltery, and a tympan, and a pipe, and an harp before them, and them prophesying.
