61 And Darius the Mede took the kingdom, being then about sixty-two years old. 2 Darius was pleased to put over the kingdom a hundred and twenty captains, who were to be all through the kingdom; 3 And over them were three chief rulers, of whom Daniel was one; and the captains were to be responsible to the chief rulers, so that the king might undergo no loss.

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.
