1 Kings 22:5-8

Moreover, Jehoshaphat said to the king of Israel, “Please inquire first for the word of the LORD.” Then the king of Israel gathered the prophets together, about four hundred men, and said to them, “Shall I go against Ramoth-gilead to battle or shall I refrain?” And they said, “Go up, for the Lord 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, because he does not prophesy good concerning me, but evil. He is Micaiah son of Imlah.” But Jehoshaphat said, “Let not the king say so.”
