Jewish and Christian Bible expositors tell us the kingdoms depict secular, Gentile world dominance throughout history symbolized in one man. Nebuchadnezzar's metallic statue is of a nude man, no clothes are given him in Daniel's description, and, therefore, Solomon's Metallic Messiah is also disrobed, comparing one nude figure against another. Below at right, the Bronze Sea with its twelve bulls is excluded because it is not part of the human anatomy. This gives the Metallic Messiah a golden head and torso, with hands, legs and feet of bronze. Only his arms and shoulders of silver need explaining.
Silver is linked to priesthood and sacrifices.
