'Band Of Prophets' in the Bible

After that you will come to Gibeah, the hill of God, where an armed force of the Philistines is stationed: and when you come to the town, you will see a band of prophets coming down from the high place with instruments of music before them; and they will be acting like prophets:

And when they came to Gibeah, a band of prophets came face to face with him; and the spirit of God came on him with power and he took his place among them as a prophet.

Now when Saul's old friends saw him among the band of prophets, the people said to one another, What has come to Saul, the son of Kish? Is even Saul among the prophets?

And Saul sent men to take David; and when they saw the band of prophets at work, with Samuel in his place at their head, the spirit of God came on Saul's men, and they became like prophets.
