There is a thought that tends to resonate with me, so I'd like your input on it, Yeshua HaDerekh. Since the Jewish holidays were basically lunar in that they followed the months which were noted by the start of the new moon, then the, say, 14th day of a month could fall on various points of the seven day Sabbath cycle and be different each year. Are you following that? For example, for Americans it's like the 4th of July happens on the 4th, not always on a certain day of the week. We're used to that. So in the year our Savior was crucified, it is possible that year that the Passover was actually a Thursday, starting at even of Wednesday. The first Passover was held in the Israelites' homes and among groups of neighbors, but later, at least after JHWH established His name in Jerusalem, people came there and the task of preparation of those hundreds and hundreds of lambs was done by the priesthood. So Wednesday would have been the slaughter day, the preparation for the dinner to be held after sunset (Wednesday even) and this would have been a Sabbath to JHWH. It would have been fitting for our Savior, the Lamb of God taking away the sins of the world, to die that day, and in order not to break the Sabbath, the observant Jews rushed to get His body laid away as best they could before sunset. Then they rested on the Sabbath of Passover, Wednesday even to Thursday even. The next day (Friday) the women prepared spices, but they rested again on the Sabbath, and this one would have been the usual weekly Sabbath. Early on the first day of the week, Mary went to the tomb and found it empty.
Along with this is another Jewish festival, the start of the Feast of Weeks. It's entirely possible that Mary went to the tomb and found it empty on the First of the Weeks, because this would have been the first day of the countdown to Pentecost. Either way, since Pentecost was the morrow after the Sabbath, this would have been to us a Sunday. Would this put our Savior in the tomb for more than three days and three nights, which He said He'd be? Not necessarily. Nobody saw His resurrection. Consider whether the preparation of the Wave offering would fit into what Yeshua fulfilled. After even on Saturday, the grain would have been harvested, prepared during the night or the early morning, and offered as the Wave Offering of the First Fruits at the appropriate time on Sunday. Isn't Yeshua the First Fruits according to Hebrews?
When I read the story this way, it makes sense to my logical time-oriented mind and doesn't require any mental gymnastics to make sense. I mention this because through the years I've heard various ways of explaining how to get three days and three nights into Friday afternoon to Sunday and I found it hard to be convinced. Looking at it this way satisfied my mind in the same way the orderliness of the universe points to His great love for us. It also places an emphasis on the plan of God which He was showing mankind from the beginning, emphasizing the fulfillment in our Messiah.
