This is "To the chief musician on the octave: a psalm of David," as in Ps. 6. It is the plaintive prayer of the gracious man in presence of growing lawlessness; then comes in the value of Jehovah's words before Himself arises to judge. Wickedness increases where righteousness was looked for. Such was the dreary state when Christ Himself was on earth, Who speaks of "this generation:" clearly a moral estimate which still abides, and will be found more and more till judgment overtake. It has nothing to do with a human life or chronology, as the context here unequivocally proves. Compare Psalm 14:5.
