The fifth verse to consider is John 19:31. “Since it was the day of Preparation, and so that the bodies would not remain on the cross on the Sabbath (for that Sabbath was a high day), the Jews asked Pilate that their legs might be broken and that they might be taken away.”
Again we come to the meaning of the phrase “day of Preparation.” Carson writes:
If paraskeuē (‘Preparation’) here refers to the same day as does its use in v. 14, and the reasoning in the notes on that verse are correct, then this sentence tells us that Jesus was crucified on Friday, the day before (i.e. the (‘Preparation’ of) the Sabbath. The next day, Sabbath (=Saturday), would by Jewish reckoning begin at sundown Friday evening. It was a special Sabbath, not only because it fell during the Passover Feast, but because the second paschal day, in this case falling on the Sabbath, was devoted to the very important sheaf offering (Lv. 23:11; cf. SB 2. 582).
The sixth verse to consider is John 19:36. “For these things took place that the Scripture might be fulfilled: ‘Not one of his bones will be broken.’”
Many Bible scholars tie the phrase “Not one of his bones will be broken” to Old Testament references to the Passover lamb in Exodus 12:46 and Numbers 9:12. The argument is that if Jesus is crucified on Passover, then this OT allusion makes more sense. Carson agrees that Jesus is portrayed as the Passover lamb throughout the New Testament, but that hardly means that his crucifixion had to be on Passover for the portrayal to make sense.
“Certainly these chapters in John are laced with the Passover motif—indeed, the same could be said for much of the Fourth Gospel, even if we dissent from those who argue that in John Jesus dies at the time the Passover lambs are being killed in the temple complex. Elsewhere in the New Testament Jesus is portrayed as the Passover lamb slain for his people (1 Cor. 5:7; 1 Pet. 1:19).”
Finally, the seventh verse to consider is John 19:42. “So because of the Jewish day of Preparation, since the tomb was close at hand, they laid Jesus there.”
Carson again notes that the day of Preparation should be understood as Friday, the day before the Sabbath. If that is the meaning of the phrase, then John’s Gospel exactly matches the chronology of the Synoptics.
