Then asked He them again, Whom seek ye? And they said, Jesus of Nazareth.
Jesus answered, I have told you that I am He: if therefore ye seek Me, let these go their way:
That the saying might be fulfilled, which He spake, Of them which Thou gavest Me have I lost none.
Once His would-be captors had regained their feet and brushed off their clothes as tried to look dignified, Jesus asked them again, “Whom seek ye?”
They answered, again, “Jesus of Nazareth.” Notice that they did not say “Jesus Christ,” or “Jesus, son of Joseph and Mary.” They were determined to give Him no honorifics, no respect. Nazareth was a little no-account, fishy-smelling dump of a town, so they were content to identify Him as being from there.
In my imagination, which does tend to go into overdrive now and then, I can see Jesus drawing an impatient breath, letting it out with a rise and fall of His shoulders and almost, but not quite, an eye-roll. He would not show disrespect to these men who had been sent on someone else’s errand. Not even to Judas, who was moments away from betraying Him.
What He said was, “I have told you that I AM. If I am the One you seek, then let these others go free.”
His words fulfilled John 6:39 and 17:12.
Jesus did not set free His power again. Once was enough to convince those who wanted to arrest Him that He could walk away, but He chose instead, after that one object lesson, to protect His disciples from harm at the hands of these officers and soldiers. It would seem that His words were enough, because we hear nothing of any attempt to restrain or harm the disciples, who probably began a quiet exit at that point.
Except for Peter.
