Daniel 1:15-17

15 and at the end of ten days their appearance hath appeared better and fatter in flesh then any of the lads who are eating the king's portion of food.

16 And the Meltzar is taking away their portion of food, and the wine of their drink, and is giving to them vegetables.

17 As to these four lads, God hath given to them knowledge and understanding in every [kind of] literature, and wisdom; and Daniel hath given instruction about every [kind of] vision and dreams.
