John Lightfoot on John 18:10

[Malchus.] A name very much in use amongst the Jews; Malluch, Nehemiah 10:4,27: Malchus the Arabian. This was also the name of that implacable enemy to Christianity Porphyrius, and of his father before him. So Luke Holsteine in the Life of Porphyrius, where he reckons up more of that name.

Christ had struck those to the ground that came to apprehend him, by the power of his word, that he might thereby provide for the flight of his disciples, and shew his own divine power. They, getting up again, accost him; Judas kisseth him; they lay hands upon him; and then Peter draws his sword, &c.
