In chapter two of Daniel, the Chaldean king Nebuchadnezzar dreams of the end of all this world’s great secular empires ... including his own. A great stone representing an eternal kingdom set up by the God of heaven destroys the image of which Babylon was the golden head.
The weak point of the statue in Nebuchadnezzar’s dream was its feet, which were a less-than-sturdy composite of iron and clay. Perhaps with this in mind, the king eventually decided to build an image of his own. His version was ninety feet high, with no weaknesses which might be easily targeted by other would-be empire builders. Anyone who observed it saw nothing but gold from head to toe.
