6:3 Then this Daniel {b} was preferred above the presidents and princes, because an excellent spirit [was] in him; and the king thought to set him over the whole realm.
(b) This heathen king preferred Daniel a stranger to all his nobles and those he was familiar with, because the graces of God were more excellent in him than in others.
6:1-5 We notice to the glory of God, that though Daniel was now very old, yet he was able for business, and had continued faithful to his religion. It is for the glory of God, when those who profess religion, conduct themselves so that their most watchful enemies may find no occasion for blaming them, save only in the matters of their God, in which they walk according to their consciences.
