11 So Daniel spoke to the guard whom the chief official had appointed over Daniel, Hananiah, Mishael, and Azariah:
12 "Why not test your servants for ten days? You could give us a diet of vegetables to eat and water to drink.
13 Then compare our appearance to the appearance of the young men who eat the king’s food. Then deal with your servants according to what you see."
14 The guard decided to go along with their plan and tested them for ten days.
15 At the end of ten days they looked better and healthier than all the young men who were eating the king’s food.
16 So the guard kept taking away their rations and the wine they were supposed to drink and gave them vegetables instead.
17 And God gave knowledge, mastery of all literature, and wisdom to these four men. Daniel himself gained understanding of every type of vision and dream.
