Matthew Henry's Concise Commentary

1:17-21 Daniel and his fellows kept to their religion; and God rewarded them with eminence in learning. Pious young persons should endeavour to do better than their fellows in useful things; not for the praise of man, but for the honour of the gospel, and that they may be qualified for usefulness. And it is well for a country, and for the honour of a prince, when he is able to judge who are best fitted to serve him, and prefers them on that account. Let young men steadily attend to this chapter; and let all remember that God will honour those who honour him, but those who despise him shall be lightly esteemed.
