Daniel 1:12-16

12“Please test your servants for ten days. Let us be given vegetables to eat and water to drink.

13Then 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.”

14He agreed with them about this and tested them for ten days.

15At the end of ten days they looked better and healthier than all the young men who were eating the king’s food.

16So the guard continued to remove their food and the wine they were to drink and gave them vegetables.
