Contradiction with Matthew 17:17
Mark 9:17 depicts a specific instance where Jesus encounters a man from the multitude seeking help, whereas Matthew 17:17 presents Jesus addressing the general faithlessness of the generation, potentially indicating a broader rebuke than the specific situation depicted in Mark.
Matthew 17:17: Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? how long shall I suffer you? bring him hither to me.
Contradiction with Luke 9:41
Luke's account includes a similar situation but places the emphasis on the overall unfaithfulness of the generation, which contrasts with the individual request for help in Mark 9:17, suggesting a discrepancy in the focus of Jesus' response.
Luke 9:41: And Jesus answering said, O faithless and perverse generation, how long shall I be with you, and suffer you? Bring thy son hither.
