Daniel 1: 11 to 13
11 Then said Daniel to the steward whom the chief of the eunuchs had set over Daniel, Hananiah, Mishael, and Azariah,
12 Prove your servants, I beseech you, for ten days and let us be given a vegetable diet and water to drink.
13 Then let our appearance and the appearance of the youths who eat of the king’s [rich] dainties be observed and compared by you, and deal with us your servants according to what you see.
