“After two days was the feast of the passover, and of unleavened bread: and the chief priests and the scribes sought how they might take him by craft, and put him to death.”
Mark 14:1 — Greek Interlinear
Church Fathers on Mark 14:1
Let us now sprinkle our book, and our thresholds, with blood, and put the scarlet thread around the house of our prayers, and bind scarlet on our hand, as was done to Zarah [Gen 38:30], that we may be able to say that the red heifer [Num 19:2] is slain in the valley [Deut 21:4]. For the Evangelist, being about to speak of the slaying of Christ, premises, 'After two days was the feast of the Passover, and of unleavened bread.'
Pascha, which in Hebrew is, phase, is not called from Passion, as many think, but from passing over, because the destroyer, seeing the blood on the doors of the Israelites, passed by them, and did not smite them; or the Lord Himself, bringing aid unto His people, walked above them.
Nevertheless, Christ Himself had determined for Himself the day of His Passion; for He wished to be crucified on the Passover, because He was the true Passover.
