What does Daniel 2:9 mean?
This statement makes it clear that Nebuchadnezzar had not forgotten his dream (Daniel 2:1); he has asked his royal astrologers and sorcerers to describe the dream to him (Daniel 2:2–3). Of course, the occultists ask the king to describe the dream, so they can tell him what it means (Daniel 2:4–7). Yet Nebuchadnezzar will not be fooled. He knows what he is doing: testing to see if these self-proclaimed diviners have real insight. If they can tell him "what" he dreamed, he can trust their ability to explain the vision. If not, then there is no reason to think they have special knowledge, at all. As the king notes, that suggests their prior advice was nothing more than lies.This incident happens early in Nebuchadnezzar's rule (Daniel 2:1), so the counselors in question may have been those appointed by his father. The text does not suggest Nebuchadnezzar had caught the advisors in lies before. Yet it hints that he did not fully trust them. Despite their pleas, the king assured his subjects he would make good on his violent threats if they could not meet his challenge.
The conjurers, ultimately, have no defense. They will admit that only a real god can know what the king asks (Daniel 2:10–11). Their rescue comes in the form of Daniel, who credits the God of Israel with providing the knowledge Nebuchadnezzar seeks (Daniel 2:27–35).
