Micaiah (mî-kâ'yah). The son of Imlah. A faithful prophet who predicted in vain to Ahab the fatal termination of his expedition against Ramoth-gilead. 1 Kings 1:22-28, 2 Chronicles 1:18-27. He delivered his warning in the form of a remarkable vision, in which the weighty lesson is conveyed that God blinds judicially those who have shut their eyes and ears to his monitions, letting them be deceived by lying spirits.
