2 Samuel 15:3

And Absalom, who had inquired also about his business, said unto him, See, thy matters are good and right, his decision being made without a thorough investigation of the matter; but there is no man deputed of the king to hear thee. The "hearers" of Oriental kings were judicial officers whose duty it was to investigate the matters brought to the king's court, the king usually deciding on the basis of their findings. It is possible that neglect and partiality had crept in without the knowledge of David, so that Absalom could avail himself of a dissatisfaction already existing.
