1. You are that tree! (19-26)
Daniel was sorry for the king's sake that he was the tree in the dream that would be cut down! Yet Daniel didn't soften the interpretation. It was God's decree against the king. He would be driven away from people and live like an animal. He had to acknowledge that God Most High is sovereign over all kingdoms and gives them to anyone he wishes. Then his kingdom would be restored.
2. Renounce your sins (27)
Daniel gave the king advice: renounce your sins and wickedness by doing right and being kind to the oppressed. Then the king's prosperity might continue. It is always good advice to renounce sin and wickedness and turn to God by doing right and being kind.
