2 Chronicles 18:3-7

And Ahab king of Israel said unto Jehoshaphat king of Judah, Wilt thou go with me to Ramoth-gilead? And he answered him, I am as thou art, and my people as thy people; and we will be with thee in the war. And Jehoshaphat said unto the king of Israel, Enquire, I pray thee, at the word of the LORD to day. Therefore the king of Israel gathered together of prophets four hundred men, and said unto them, Shall we go to Ramoth-gilead to battle, or shall I forbear? And they said, Go up; for God will deliver it into the king's hand. But Jehoshaphat said, Is there not here a prophet of the LORD besides, that we might enquire of him? 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.
