So the question is this...if it was all through vision, how did they all have the same vision that Joe down the road didn't come along and say, "nope, in my dream, the cherubim looked like this..." and Sally walked into the tabernacle and said, "nope you got it wrong, God told me in a dream that they looked like this..." etc.
