Daniel 1:8-16

But Daniel was determined not to defile himself by eating the food and wine given to them by the king. He asked the chief of staff for permission not to eat these unacceptable foods. Now God had given the chief of staff both respect and affection for Daniel. But he responded, “I am afraid of my lord the king, who has ordered that you eat this food and wine. If you become pale and thin compared to the other youths your age, I am afraid the king will have me beheaded.” Daniel spoke with the attendant who had been appointed by the chief of staff to look after Daniel, Hananiah, Mishael, and Azariah. “Please test us for ten days on a diet of vegetables and water,” Daniel said. “At the end of the ten days, see how we look compared to the other young men who are eating the king’s food. Then make your decision in light of what you see.” The attendant agreed to Daniel’s suggestion and tested them for ten days. At the end of the ten days, Daniel and his three friends looked healthier and better nourished than the young men who had been eating the food assigned by the king. So after that, the attendant fed them only vegetables instead of the food and wine provided for the others.
