61 It pleased Darius to set over the kingdom a hundred and twenty satraps, to be throughout the whole kingdom; 2 and over them three presidents, of whom Daniel was one, to whom these satraps should give account, so that the king might suffer no loss. 3 Then this Daniel became distinguished above all the other presidents and satraps, because an excellent spirit was in him; and the king planned to set him over the whole kingdom.

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.
