'Prophesying' in the Bible

And the king of Israel saith unto Jehoshaphat, 'Still -- one man to seek Jehovah from him, and I -- I have hated him, for he is not prophesying concerning me of good, but all his days of evil, he is Micaiah son of Imlah;' and Jehoshaphat saith, 'Let not the king say so.'

Now the king of Israel and King Jehoshaphat of Judah, clothed in royal attire, were each sitting on his own throne. They were sitting on the threshing floor at the entrance to Samaria’s gate, and all the prophets were prophesying in front of them.

And all the prophets were prophesying the same, saying, “March up to Ramoth-gilead and succeed, for the Lord will hand it over to the king.”

While he was speaking, Amaziah said to him, "Did we appoint you to be a royal counselor? Stop prophesying or else you will be killed!" So the prophet stopped, but added, "I know that the Lord has decided to destroy you, because you have done this thing and refused to listen to my advice."
