Adam Clarke on Daniel 6:28

So this Daniel prospered - He had served fine kings: Nebuchadnezzar, Evil-merodach, Belshazzar, Darius, and Cyrus. Few courtiers have had so long a reign, served so many masters without flattering any, been more successful in their management of public affairs, been so useful to the states where they were in office, or have been more owned of God, or have left such an example to posterity.

Where shall we find ministers like Samuel and Daniel? None so wise, so holy, so disinterested, so useful, have ever since appeared in the nations of the earth.
