11 So Daniel said to the guard whom the chief official had assigned to Daniel, Hananiah, Mishael, and Azariah,
12 “Please test your servants for 10 days. Let us be given vegetables to eat and water to drink.
13 Then examine our appearance and the appearance of the young men who are eating the king’s food, and deal with your servants based on what you see.”
14 He agreed with them about this and tested them for 10 days.
15 At the end of 10 days they looked better and healthier than all the young men who were eating the king’s food.
16 So the guard continued to remove their food and the wine they were to drink and gave them vegetables.
17 God gave these four young men knowledge and understanding in every kind of literature and wisdom. Daniel also understood visions and dreams of every kind.
