Daniel 1:13 WEB

¹¹  Then said Daniel to the steward whom the prince of the eunuchs had appointed over Daniel, Hananiah, Mishael, and Azariah:

¹²  Prove your servants, I beg you, ten days; and let them give us pulse to eat, and water to drink.

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.
