Micaiah
   who is like Jehovah?, the son of Imlah, a faithful prophet of
   Samaria (1 Kings 22:8-28). Three years after the great battle
   with Ben-hadad (20:29-34), Ahab proposed to Jehoshaphat, king of
   Judah, that they should go up against Ramoth-Gilead to do battle
   again with Ben-hadad. Jehoshaphat agreed, but suggested that
   inquiry should be first made "at the word of Jehovah." Ahab's
   prophets approved of the expedition; but Jehoshaphat, still
   dissatisfied, asked if there was no other prophet besides the
   four hundred that had appeared, and was informed of this
   Micaiah. He was sent for from prison, where he had been
   confined, probably on account of some prediction disagreeable to
   Ahab; and he condemned the expedition, and prophesied that it
   would end, as it did, in disaster. We hear nothing further of
   this prophet. Some have supposed that he was the unnamed prophet
   referred to in 1 Kings 20:35-42.
