{He perceived} (egin(9373)ken). Imperfect tense descriptive
of Pilate's growing apprehension from their conduct which
increased his intuitive impression at the start. It was gradually
dawning on him. Both Mark and Matthew give "envy" (phthonon) as
the primary motive of the Sanhedrin. Pilate probably had heard of
the popularity of Jesus by reason of the triumphal entry and the
temple teaching. {Had delivered} (paraded(936b)eisan). Past perfect
indicative without augment where  Mt 27:18  has the first aorist
(kappa aorist) indicative pared(936b)an, not preserving the
distinction made by Mark. The aorist is never used "as" a past
perfect.
