oatmeal,
re: "yes, he died on Wednesday, was buried before sunset and God raised him on Saturday, 72 hours later."
The problem with that scenario is that there are 4 daytimes involved.
Now after the Sabbath, as the first day of the week began to dawn... (Matthew 28:1 NKJV)
The word "dawn" is translated from the Greek
epiphosko, in this case the dawn of a twelve hour day.
This same Greek word is used in Luke 23:54.
That day was the Preparation, and the Sabbath drew near. (Luke 23:54 NKJV)
The term "drew near" is an obfuscation of
epiphosko which means dawn, in this case the beginning of a twenty-four hour day.
A trumpet signaled the beginning of each Sabbath which is how they knew the Sabbath had dawned (began).
Seventy-two hours later Christ was restored to immortality as Sunday began.
The tomb was sealed and a guard posted until Sunday.
On the next day, which followed the Day of Preparation, the chief priests and Pharisees gathered together to Pilate saying, “Sir, we remember, while He was still alive how that deceiver said, ‘After three days I will rise.’ Therefore command that the tomb be made secure until the third day lest His disciples come by night and steal Him away and say to the people, ‘He has risen from the dead.’ So the last deception will be worse than the first.”
Pilate said to them, “You have a guard, go your way, make it as secure as you know how.”
So they went and made the tomb secure, sealing the stone and setting the guard. (Matthew 27:62-66 NKJV)
