2 Chronicles 18:5-7

So the king of Israel summoned the prophets, 400 of them, and asked them, “Should we go to war against Ramoth-gilead, or should I hold back?” They all replied, “Yes, go right ahead! God will give the king victory.” But Jehoshaphat asked, “Is there not also a prophet of the LORD here? We should ask him the same question.” The king of Israel replied to Jehoshaphat, “There is one more man who could consult the LORD for us, but I hate him. He never prophesies anything but trouble for me! His name is Micaiah son of Imlah.” Jehoshaphat replied, “That’s not the way a king should talk! Let’s hear what he has to say.”
