Daniel 1:11-17

¹¹Then said Daniel to Melzar, whom the prince of the eunuchs had set over Daniel, Hananiah, Mishael, and Azariah, ¹²Prove thy servants, I beseech thee, ten days; and let them give us pulse to eat, and water to drink. ¹³Then let our countenances be looked upon before thee, and the countenance of the children that eat of the portion of the king's meat: and as thou seest, deal with thy servants.

¹⁴So he consented to them in this matter, and proved them ten days. ¹⁵And at the end of ten days their countenances appeared fairer and fatter in flesh than all the children which did eat the portion of the king's meat. ¹⁶Thus Melzar took away the portion of their meat, and the wine that they should drink; and gave them pulse.

¹⁷As for these four children, God gave them knowledge and skill in all learning and wisdom: and Daniel had understanding in all visions and dreams.
