1Ki 22:8
Ahab then named to him one, but one whom he hated, because he never prophesied good concerning him, but only evil, namely, Micah the son of Jimlah. Josephus and the Rabbins suppose him to have been the prophet, whose name is not given, who had condemned Ahab in the previous war for setting Benhadad at liberty (1Ki 20:35.). But there is no foundation for this, and it is mere conjecture. At any rate, Ahab had already come to know Micah as a prophet of evil, and, as is evident from 1Ki 22:26, had had him imprisoned on account of an unwelcome prophecy. Ahab’s dislike to this prophet had its root in the belief, which was connected with heathen notions of prophecy and conjuring, that the prophets stood in such a relation to the Deity that the latter necessarily fulfilled their will; a belief which had arisen from the fact that the predictions of true prophets always came to pass (see at Num 22:6 and Num 22:17).
