4 Then the presidents and the satraps sought to find a ground for complaint against Daniel with regard to the kingdom; but they could find no ground for complaint or any fault, because he was faithful, and no error or fault was found in him. 5 Then these men said, "We shall not find any ground for complaint against this Daniel unless we find it in connection with the law of his God."
Matthew Henry's Commentary on Daniel 6:4-5
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.
