Mark 15:10

He perceived (eginwsken). 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" (pqonon) 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 (paradedwkeisan). Past perfect indicative without augment where Matthew 27:18 has the first aorist (kappa aorist) indicative paredwkan, not preserving the distinction made by Mark. The aorist is never used "as" a past perfect.
