2nd Chronicles 18:8

5 Therefore the king of Israel gathered together of prophets four hundred men, and said unto them, Shall we go to Ramothgilead to battle, or shall I forbear? And they said, Go up; for God will deliver it into the king's hand.

6 But Jehoshaphat said, Is there not here a prophet of the LORD besides, that we might enquire of him?

7 And the king of Israel said unto Jehoshaphat, There is yet one man, by whom we may enquire of the LORD: but I hate him; for he never prophesied good unto me, but always evil: the same is Micaiah the son of Imla. And Jehoshaphat said, Let not the king say so.

8 And the king of Israel called for one of his officers, and said, Fetch quickly Micaiah the son of Imla.

9 And the king of Israel and Jehoshaphat king of Judah sat either of them on his throne, clothed in their robes, and they sat in a void place at the entering in of the gate of Samaria; and all the prophets prophesied before them.

10 And Zedekiah the son of Chenaanah had made him horns of iron, and said, Thus saith the LORD, With these thou shalt push Syria until they be consumed.

11 And all the prophets prophesied so, saying, Go up to Ramothgilead, and prosper: for the LORD shall deliver it into the hand of the king.
