And Micaiah said, as the Lord liveth,.... He swore by the living God, for the confirmation of what he was about to say:
what the Lord saith unto me, that will I speak; truly and faithfully, keeping nothing back, nor adding anything, whether it be good or evil, pleasing or displeasing; it looks as if as yet he had no instruction from the Lord what to say, and yet the vision he later declares seems to have been had by him before, 1 Kings 22:17.
