Daniel 1:12-20

12“Please test your servants for ten days: Give us nothing but vegetables to eat and water to drink. 13Then compare our appearance with that of the young men who eat the royal food, and treat your servants in accordance with what you see.”

14So he agreed to this and tested them for ten days. 15At the end of the ten days they looked healthier and better nourished than any of the young men who ate the royal food.

16So the guard took away their choice food and the wine they were to drink and gave them vegetables instead.

17To these four young men God gave knowledge and understanding of all kinds of literature and learning. And Daniel could understand visions and dreams of all kinds. 18At the end of the time set by the king to bring them into his service, the chief official presented them to Nebuchadnezzar. 19The king talked with them, and he found none equal to Daniel, Hananiah, Mishael and Azariah; so they entered the king’s service.

20In every matter of wisdom and understanding about which the king questioned them, he found them ten times better than all the magicians and enchanters in his whole kingdom.
