Matthew 17:17

Matthew 17:17. Unbelieving and perverse generation. The failure to cure, the catechizing of the scribes, and the effect produced on the people, proved that all present were unbelieving and liable to be led astray. But the term ‘generation' requires a still wider reference to the race and generation, whom this company represented.

How long shall I be with you? An expression of displeasure. He would not long remain on earth and bear with their unbelief and perversity. Less probably, it means that the disciples soon could not have Him to come thus personally to supply their lack of faith and power.

To me, emphasizing His power, despite the failure of the disciples. Mark (Mark 9:20-25) narrates a fearful paroxysm in the lad when brought to Jesus; a description of his case from the father with a new entreaty; the challenge given by our Lord to his faith, and his humble, tearful answer; the movement of the crowd excited by the previous failure and controversy; the language addressed to the evil spirit.
