What does Daniel 4:8 mean?
After a troubling dream (Daniel 4:4–5), Nebuchadnezzar put out a summons to all the wise men of his kingdom. That suggests that Daniel, already proven at interpreting dreams (Daniel 2:19), was also called. Yet because of his important position (Daniel 2:48), he was probably not available as quickly as the court occultists. When the king says that Daniel came in "at last," it refers to anticipation, not a suggestion that Daniel was literally the last person consulted.It's also possible the king was hoping to get a happier answer from his magicians than he expected from Daniel. Many years before Nebuchadnezzar, Israel's King Ahab put off speaking with a prophet of God (1 Kings 22:8) because he didn't like what that prophet often had to say. In fact, Ahab mistreated God's messenger for faithfully delivering bad news (1 Kings 22:26–28).
Nebuchadnezzar's program for Hebrew captives (Daniel 1:1–5) included renaming the captives to cement their identity as servants of Babylon (Daniel 1:6–7). Because of Daniel's prior success, the king sees him as one in direct contact with divine beings. As a pagan, and worshipper of many false gods, the king consulted with idols before seeking an answer from someone who served the true God. Unbelievers often resort to unreliable sources for answers to their problems before turning to God as a last resort. Yet Nebuchadnezzar remembered that Daniel had interpreted his previous frightening dream.
