A common misinterpretation views this verse as a blanket condemnation of all previous religious leaders or prophets like Moses, Abraham, or David, dismissing the Old Testament entirely; however, Jesus targets contemporary false messiahs and self-appointed shepherds who bypassed God's ordained way, not the faithful prophets who pointed forward to Him, as evidenced by His frequent affirmations of Scripture and the prophets throughout the Gospels.
John 10:8
King James Version (1769)
8 All that ever came before me are thieves and robbers: but the sheep did not hear them.
Jesus declares His exclusive role as the legitimate Shepherd and door to salvation, contrasting Himself with all prior false claimants—thieves and robbers—who sought to exploit the flock for personal gain rather than lead them to abundant life; true sheep, attuned to His voice, instinctively reject these impostors and follow only Him, emphasizing the discernment provided by genuine faith.
