Daniel 1:15-21

And when the ten days were completed, they looked healthier and had even gained weight. The four Hebrew young men were in better physical condition compared to any of the others who had eaten their food from the royal table. So the guard replaced their diet of royal food and wine with vegetables and water. God imparted insight and skill in every aspect of literature and science to the four Hebrew men. Daniel also had the unique gift of interpreting every kind of supernatural vision and dream. At the end of the period that the king had assigned for their training, the chief of the palace servants brought them to Nebuchadnezzar’s court. The king interviewed them all, and among all the young men, he found none to equal Daniel, Hananiah, Mishael, and Azariah. So, the king chose them to serve as his advisers. And when the king questioned them on any point of wisdom or understanding, he found them ten times superior to all the magicians and enchanters in his entire kingdom. And Daniel continued there in Babylon as a royal adviser until the time Cyrus became king.
