4:9–12. Nebuchadnezzar referred to Daniel as chief of the magicians, not because he was in authority over the wise men but because he was wiser than all of them, capable of understanding and interpreting dreams. The king implored Daniel to interpret his dream for him. Nebuchadnezzar’s dream was a simple one. He was perplexed not by what he had seen, but by his inability to understand its meaning.
Previously Nebuchadnezzar had traveled to Lebanon to watch the felling of the great cedars to provide timber for his construction projects in Babylon. So he had witnessed the felling of mighty trees. The tree he saw in his dream was significant because of its size (vv. 10–11), its beauty (v. 12), and its fruit (v. 12). It provided food and shelter for all the animals and birds who lived under it or in it.
