In this passage Jesus says to the Pharisees and Lawyers: You look ok on the outside, but really you are not ok on the inside. Jesus doesn't ever wound for the sake of inflicting pain. Jesus is going to reveal their deepest faults so that they can be cleansed from within.
The entire story of God and his people culminates into a figure of hope that would come at the promise of god, a King. Look with us as we see that this King whom God has raised up is realized at the coming of Jesus, God’s promised King.
