15 At the end of ten days their faces appeared fairer, and they were fatter in flesh, than all the youths who ate of the king's dainties.

Daniel 1:15 In-Context

13 Then let our faces be looked on before you, and the face of the youths who eat of the king's dainties; and as you see, deal with your servants.
14 So he listened to them in this matter, and proved them ten days.
15 At the end of ten days their faces appeared fairer, and they were fatter in flesh, than all the youths who ate of the king's dainties.
16 So the steward took away their dainties, and the wine that they should drink, and gave them pulse.
17 Now as for these four youths, God gave them knowledge and skill in all learning and wisdom: and Daniyel had understanding in all visions and dreams.
