“As soon then as he had said unto them, I am he, they went backward, and fell to the ground.”
King James Version (KJV)
18:6 As soon as he said, I am he, they went backward and fell to the ground - How amazing is it, that they should renew the assault, after so sensible an experience both of his power and mercy! But probably the priests among them might persuade themselves and their attendants, that this also was done by Beelzebub; and that it was through the providence of God, not the indulgence of Jesus, that they received no farther damage.
Joh 18:6 They went backward, and fell to the ground. This statement of John is omitted by the other gospels. As Christ answers them, either his majesty and their own terror so impressed them, that, awed, they fell backward to the earth, or his divine power was exerted to prostrate them. Then the Lord submitted himself "as a lamb to the slaughter" (Isa 53:7 Jer 11:19 Ac 8:32), and his power is not again exerted until he rises from the tomb, except to heal the smitten servant of the high priest.
