"And one of them struck the servant of the high priest, cutting off his right ear. But Jesus answered, “No more of this!” And he touched the man’s ear and healed him."
Jesus never used violent uprisings to get his way. Unlike the rebellious zealots who went before him, Jesus's power and authority come from faith and truth. He need not even lift a finger against his enemies to establish his dominance although he easily could.
This is why the ear was cut off. His disciples trusted in his power to defeat his mortal enemies. If Jesus was to become King and overthrow the Roman government and give the Jews back their land, now was the time. This is the time for battle. This would be the ear-cutting heard round the world. This is the start of the revolution! The time is now and the kingdom of God is at hand! Strike and believe the good news!
But that's not how it goes.
Jesus undoes what happened to that servant's ear and in front of everyone performs a miracle, demonstrating again his power and authority and command of the situation. And they still took him, but we know the truth. Jesus allowed himself to be taken. No more mysteriously passing through crowds as we see in the Gospel of John. Now is the time, the hour when darkness reigns. The Kingdom of God is coming, and soon all Hell will break loose.
