A prophet in Israel whom King Ahab detested because he offered pessimistic prophecies when questioned. Ahab and Jehoshaphat, King of Judah, were planning a war to capture Ramoth-Gilead, and the official prophets, four hundred strong, assured Ahab that the campaign would be successful. But when Micaiah was consulted, he stubbornly insisted that the attack would be disastrous. The infuriated king had him thrown into prison and accepted the optimistic opinion of the four hundred. In the battle that followed Ahab was so badly wounded he died the same day. Micaiah was vindicated (I Kings 22).
