2 Chronicles 18:5-7

Then the king of Israel assembled the prophets, four hundred men, and said to them, “Shall we go against Ramoth-gilead to battle, or shall I refrain?” And they said, “Go up, for God will give it into the hand of the king.” But Jehoshaphat said, “Is there not yet a prophet of the LORD here that we may inquire of him?” The king of Israel said to Jehoshaphat, “There is yet one man by whom we may inquire of the LORD, but I hate him, for he never prophesies good concerning me but always evil. He is Micaiah, son of Imla.” But Jehoshaphat said, “Let not the king say so.”
