61 It pleased Darius to set over the kingdom one hundred and twenty satraps, to be over the whole kingdom; 2 and over these, three governors, of whom Daniel was one, that the satraps might give account to them, so that the king would suffer no loss. 3 Then this Daniel distinguished himself above the governors and satraps, because an excellent spirit was in him; and the king gave thought to setting him over the whole realm.

Commentary on Daniel 6:1-5
(Read Daniel 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.
