47 And while He was still speaking, behold, a multitude; and he who was called Judas, one of the twelve, went before them and drew near to Jesus to kiss Him. 48 But Jesus said to him, “Judas, are you betraying the Son of Man with a kiss?”
49 When those around Him saw what was going to happen, they said to Him, “Lord, shall we strike with the sword?” 50 And one of them struck the servant of the high priest and cut off his right ear.
51 But Jesus answered and said, “Permit even this.” And He touched his ear and healed him.
52 Then Jesus said to the chief priests, captains of the temple, and the elders who had come to Him, “Have you come out, as against a robber, with swords and clubs? 53 When I was with you daily in the temple, you did not try to seize Me. But this is your hour, and the power of darkness.”
Luke 22:47-53
Betrayal and arrest at Gethsemane. A multitude of armed soldiers along with members of the Sanhedrin show up to arrest Jesus, led by Judas. Judas approached Christ and betrayed Him with a kiss, as even though He had taught all week in the temple and apparently tormented the Sanhedrin enough to warrant His death… They had no clue what he actually looked like. They could not recognize Him in a crowd.
Peter then lashed out with a sword to try and defend, but Christ quickly rebuked him, telling him to permit what was happening. By healing the servant, Jesus removed the evidence of the crime which Peter had committed and spared him a similar fate (for now). Jesus looked to the multitude and admitted that this was their hour, as they displayed the power of darkness in contrast to His light.
