Peter Pett's Commentary on the Bible
Daniel 3 - Introduction
Chapter 3 The Great Image of Nebuchadnezzar And Salvation from the Fiery Furnace.
This chapter following chapter 2 seems to confirm that Nebuchadnezzar had seen the image that he had envisioned there as representing the gods. Probably what Daniel had told him, with its suggestion of his empire finally being replaced, had concerned him and had given him the idea of setting up such an image as representing the god who was over the empire (possibly Marduk or Nebo, compare Roma), and requiring a great demonstration of loyalty. Only his image would be superior to the one that he had seen. It would be all of gold. There would be no suggestion of some empire following his. There was certainly no doubt that he wanted it to reflect well on himself. And it would confirm the loyalty of the people, and fill them with awe at his magnificence. But the fact that there is no suggestion made that it was an image of himself counts against it being so, otherwise it would surely have been pointed out.
