John 18:5-6
Considering that the "He" in italics is not in the original text, I believe that He said, "I am". So what made the troops fall back to the ground?They answered Him, “Jesus of Nazareth.”
Jesus said to them, “I am He.” And Judas, who betrayed Him, also stood with them. 6 Now when He said to them, “I am He,” they drew back and fell to the ground.
