4 Then the presidents and satraps have been seeking to find a cause of complaint against Daniel concerning the kingdom, and any cause of complaint and corruption they are not able to find, because that he 'is' faithful, and any error and corruption have not been found in him.
Matthew Henry's Commentary on Daniel 6:4
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.
