Crucify him, crucify him (staurōson, staurōson). First aorist active imperative of stauroō for which verb see Mat 20:19, etc. Here the note of urgency (aorist imperative) with no word for “him,” as they were led by the chief priests and the temple police till the whole mob takes it up (Mat 27:22).
For I find no crime in him (egō gar ouch heuriskō). This is the third time Pilate has rendered his opinion of Christ’s innocence (Joh 18:38; Joh 19:4). And here he surrenders in a fret to the mob and gives as his reason (gar, for) for his surrender the innocence of Jesus (the strangest judicial decision ever rendered). Perhaps Pilate was only franker than some judges!
