Daniel 1:8-16
1:8 But Daniel made up his mind that he would not defile himself with the royal delicacies or the royal wine. He therefore asked the overseer of the court officials for permission not to defile himself.
1:9 Then God made the overseer of the court officials sympathetic to Daniel.
1:10 But he responded to Daniel, “I fear my master the king. He is the one who has decided your food and drink. What would happen if he saw that you looked malnourished in comparison to the other young men your age? If that happened, you would endanger my life with the king!”
1:11 Daniel then spoke to the warden whom the overseer of the court officials had appointed over Daniel, Hananiah, Mishael, and Azariah:
1:12 “Please test your servants for ten days by providing us with some vegetables to eat and water to drink.
1:13 Then compare our appearance with that of the young men who are eating the royal delicacies; deal with us in light of what you see.”
1:14 So the warden agreed to their proposal and tested them for ten days.
1:15 At the end of the ten days their appearance was better and their bodies were healthier than all the young men who had been eating the royal delicacies.
1:16 So the warden removed the delicacies and the wine from their diet and gave them a diet of vegetables instead.
