Theodoret of Cyrus : So here he informs us of the king's generosity in providing them with nourishment that was not of an ordinary kind fit for captives and slaves; instead, he gave orders for them to share in the king's table. Shortly afterward he mentions their self-control and sound values, not indulging in self-glorification but proposing a beneficial lesson to those prepared to accept benefit. It is possible to see also the moderation in his thinking: after mentioning above that the king ordered young men of royal birth to be chosen, fair to behold and of becoming stature, and citing at this point the persons' names, he simply referred to the tribe of Judah and concealed their royal connections. — COMMENTARY ON Daniel 1:5-6
