'Prophets' in the Bible

Then the Lord came down in the cloud and had talk with him, and put on the seventy men some of the spirit which was on him: now when the spirit came to rest on them, they were like prophets, but only at that time.

And a young man went running to Moses and said, Eldad and Medad are acting as prophets in the tent-circle.

And Moses said to him, Are you moved by envy on my account? If only all the Lord's people were prophets, and the Lord might put his spirit on them!
