Daniel 1:12-14
Daniel 1: 12 to 14
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.
14 So [the man] consented to them in this matter and proved them ten days.
