And every one had four faces.These living creatures were probably hieroglyphical representations of the holy angels, the attendants on "the King of Glory," and the ministers of his providence. They were four, apparently to denote that they were employed in the four corners of the world; and they had the likeness of a man, to signify that they were intelligent and rational creatures.
