Daniel 1:14-20

So the guard agreed to test them for ten days. After ten days they looked healthier and better fed than all the young men who ate the king’s food. So the guard took away the king’s special food and wine, feeding them vegetables instead. God gave these four young men wisdom and the ability to learn many things that people had written and studied. Daniel could also understand visions and dreams. At the end of the time set for them by the king, Ashpenaz brought all the young men to King Nebuchadnezzar. The king talked to them and found that none of the young men were as good as Daniel, Hananiah, Mishael, and Azariah. So those four young men became the king’s servants. Every time the king asked them about something important, they showed much wisdom and understanding. They were ten times better than all the fortune-tellers and magicians in his kingdom!
