That it was out of jealousy
That the chief priests
Had handed him over.”
ἐγίνωσκεν γὰρ ὅτι διὰ φθόνον παραδεδώκεισαν αὐτὸν οἱ ἀρχιερεῖς.
This is something almost word for word in Matthew, chapter 27:18. Mark said that Pilate knew or realized (ἐγίνωσκεν γὰρ) that it was out of jealousy (ὅτι διὰ φθόνον) that the chief priests had handed Jesus over to him (παραδεδώκεισαν αὐτόν οἱ ἀρχιερεῖς). Pilate was a cagey guy. Do you act out of jealousy?
