And, behold, there came a prophet unto Ahab king of Israel, saying, Thus saith the LORD, Hast thou seen all this great multitude? behold, I will deliver it into thine hand this day; and thou shalt know that I am the LORD. There came a prophet - Who this was we cannot tell; Jarchi says it was Micaiah, son of Imlah. It is strange that on such an occasion we hear nothing of Elijah or Elisha. Is it not possible that this was one of them disguised?
