And a Cherub is standing in each direction but the wings of the Cherubim surround each other above their heads in glory; and they spread them to sing with them a song to him that inhabits the clouds and to praise the fearful majesty of the king of kings with their wings. The sound coming from their wings is heard as a song. This hearkens back to a description of Lucifer, before the fall. It was said that his body had instruments made within it, which made beautiful music.
