Charles Ellicott Commentary 2 Samuel 15:3

"And Absalom said unto him, See, thy matters are good and right; but there is no man deputed of the king to hear thee." — 2 Samuel 15:3 (ASV)

There is no man deputed of the king. —There is no official hearer appointed. It was impossible for the king to hear every case in detail; certain persons were therefore appointed to hear cases and report the facts to the king, who then pronounced his judgment. Absalom uses the same tactics which have been used by the demagogue in all ages. He does not accuse the king himself of wrong, but insinuates that the system of government is defective, and expresses his own earnest wish to set things right.
