'Prophets' in the Bible

After that you will come to the hill of God where the garrison of the Philistines is; and when you come there to the city, you will meet a group of prophets coming down from the high place [of worship] with harp, tambourine, flute, and lyre before them, and they will be prophesying.

When they came to the hill [Gibeah], behold, a group of prophets met him; and the Spirit of God came on him mightily, and he prophesied [under divine guidance] among them.

Now when all who knew Saul previously saw that he actually prophesied now [by inspiration] with the prophets, the people said one to another, “What has happened to [Saul, who is nobody but] the son of Kish? Is Saul also among the prophets?”

And a man from there answered, “But who is the father of the others?” So it became a proverb, “Is Saul also among the prophets?”

Then Saul sent messengers to take David; but when they saw the group of prophets prophesying, and Samuel standing and presiding over them, the Spirit of God came on the messengers of Saul; and they also prophesied.

He also took off his [royal] robes [and armor] and prophesied before Samuel and lay down naked all that day and night. So they say, “Is Saul also among the prophets?”

So Saul inquired of the Lord, but the Lord did not answer him, either by dreams or by Urim [used like lots by the priest to determine the will of God] or by prophets.

Then Samuel said to Saul, “Why have you disturbed me by bringing me up?” Saul answered, “I am greatly distressed; for the Philistines are making war against me, and God has left me and no longer answers me, either through prophets or by dreams; therefore I have called you to make known to me what I should do.”
