Matthew 27:62-64 (NASB)
62 Now on the next day, the day after the preparation, the chief priests and the Pharisees gathered together with Pilate, 63 and said, "Sir, we remember that when He was still alive that deceiver said, 'After three days I am to rise again.' 64 "Therefore, give orders for the grave to be made secure until the third day, otherwise His disciples may come and steal Him away and say to the people, 'He has risen from the dead,' and the last deception will be worse than the first."
If the day after Y'shua was crucified and entombed was the day after the preparation, that would mean that Y'shua was crucified on the day of preparation. If that was the day of preparation for the weekly Sabbath (sunset Thursday to sunset Friday), that would mean that Y'shua was placed in the tomb Friday before sunset. If Y'shua was resurrected by sunrise on Sunday, then Y'shua was only “in the heart of the earth” two nights and one day.
Night 1: Friday evening (~6pm to 6am Saturday Morning)
Day 1: Saturday daytime (~6am to 6pm)
Night 2: Saturday night (~6pm to 6am Sunday morning)
Matthew records that Y'shua specifically prophesied that he would be in the tomb three days and three nights.
Matthew 12:38-40 (NASB)
38 Then some of the scribes and Pharisees said to Him, "Teacher, we want to see a sign from You." 39 But He answered and said to them, "An evil and adulterous generation craves for a sign; and yet no sign will be given to it but the sign of Jonah the prophet; 40 for just as JONAH WAS THREE DAYS AND THREE NIGHTS IN THE BELLY OF THE SEA MONSTER, so will the Son of Man be three days and three nights in the heart of the earth.
If the “Preparation Day mentioned in Matthew 27:62-64 was for the weekly Sabbath and not for Passover, it would mean that Y'shua was only in the grave for two nights and one day. This would make Y'shua a false prophet who could not therefore be the Messiah. If however, the “Preparation Day” of Matthew 27:62-64 was the preparation day for Passover, which fell on a Wednesday the year Y'shua died, then Y'shua’s prophesy would have been fulfilled to the letter.
Night 1: Wednesday evening (~6pm to 6am Thursday)
Day 1: Thursday daytime (6am to 6 pm)
Night 2: Thursday evening (~6pm to 6am Friday)
Day 2: Friday daytime (~6am to 6pm)
Night 3: Friday evening (~6pm to 6am Saturday)
Day 3: Saturday day time (~ 6am to sunset)
The Preparation day mentioned in Matthew 27:62-64 therefore had to have been the preparation day for Passover which means that the “Last Supper” could not have been the Passover. Likewise the Preparation Day mentioned in Luke 23:54; Mark 15:42; and John 19:14; was the Preparation Day for Passover.
In my next post I will explore what Scripture says about falsehoods like the doctrine that the Last Supper was the Passover.
 Y'shua was resurrected sometime between sunset Saturday and sunrise Sunday when the tomb was found to be empty.
