Daniel made up his mind to eat and drink only what God had approved for his people to eat. And he asked the king’s chief official for permission not to eat the food and wine served in the royal palace. God had made the official friendly and kind to Daniel. But the man still told him, “The king has decided what you must eat and drink. And I am afraid he will kill me, if you eat something else and end up looking worse than the other young men.”
The king’s official had put a guard in charge of Daniel and his three friends. So Daniel said to the guard, “For the next ten days, let us have only vegetables and water at mealtime. When the ten days are up, compare how we look with the other young men, and decide what to do with us.” The guard agreed to do what Daniel had asked.
Ten days later, Daniel and his friends looked healthier and better than the young men who had been served food from the royal palace. After this, the guard let them eat vegetables instead of the rich food and wine.
God made the four young men smart and wise. They read a lot of books and became well educated. Daniel could also tell the meaning of dreams and visions. [Daniel 1:8-17]
