They answered him, Jesus of Nazareth. Jesus said unto them,
I am he.
And Judas also, who betrayed him, stood with them.
All Commentaries on John 18:5 Go To John 18
Do you see His invincible power, how being in the midst of them He disabled their eyes? For that the darkness was not the cause of their not knowing Him, the Evangelist has shown, by saying, that they had torches also. And even had there been no torches, they ought at least to have known Him by His voice; or if they did not know it, how could Judas be ignorant, who had been so continually with Him? For he too stood with them, and knew Him no more than they, but with them fell backward. And Jesus did this to show, that not only they could not seize Him, but could not even see Him when in the midst, unless He gave permission.
