{Fell to the ground} (epesan chamai). Second aorist active
indicative of pipt(935c) with first aorist ending (-an). This
recoil made them stumble. But why did they step back? Was it the
former claim of Jesus ({I am}, eg(9320)eimi) to be on an equality

supernatural power exerted by Jesus? B adds I(8873)ous which must
mean simply: "I am Jesus."
