ESV Study Bible explains the purpose of these detailed prophecies, noting that although Judah was about to be restored from exile, and yet it was not really free. It would be subject to the Persians, and then to Alexanders Greeks; after that it would be caught in the middle between powerful heirs of Alexanders empire, the Seleucids and the Ptolemies. Pious Jews would readily fall into bewilderment: how do these circumstances display Gods concern for His people, and how will God ever use His now-insignificant people to bring blessing to the whole world? The vision is therefore reassurance for the faithful.

“Bureaucrats derive their power from their position in the structure, not from their relations with the people they are supposed to serve. The people are not masters of the bureaucracy, but its clients. They receive its services, but only insofar as they conform to its authority. The bureaucracy is like a computer, it responds only to those who address it in the proper form. In this sense, a bureaucratic government program has a double meaning. The program serves its clients, but it also programs them.”
