'Company Of Prophets' in the Bible

After that thou shalt come to the hill of God, where is the garrison of the Philistines: and it shall come to pass, when thou art come thither to the city, that thou shalt meet a company of prophets coming down from the high place with a psaltery, and a tabret, and a pipe, and a harp, before them; and they shall prophesy:

And when they came thither to the hill, behold, a company of prophets met him; and the Spirit of God came upon him, and he prophesied among them.
