Daniel 1:11-13

11And Daniel said to the steward, 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 youths that eat of the king's delicate food: and as thou shalt see, deal with thy servants.
