The Messiah and the 3 days and 3 nights timeframe of Matthew 12:40?

No. Just the number of days and nights He was in His tomb. Luke 24:20-21, ". . . And how the chief priests and our rulers delivered him to be condemned to death, and have crucified him. But we trusted that it had been he which should have redeemed Israel: and beside all this, to day is the third day since these things were done. . . ."

 

The first day of the week was explicitly the third day since He was crucified. The third day, it's start of a day and its full night. The second day was the Sabbath, a full night and day. He was placed in His tomb after sundown our Thursday when the 15th ended, the beginning of the Preparation Day, the day before the Sabbath, a full night and day. So three full nights, two full days, and on the beginning of the third day His resurrection.

 

There are actual historical dates for the death, burial and resurrection.

Julian dates April 6th Thursday through the 9th Sunday 30 A.D. Per Mark 14:12 to Mark 16. Mark 14:12 being April 5th the Wednesday.

This can be a wrong process of reckoning.

You're using the word "explicitly", so that puts me at a disadvantage, I suppose.

Anyway. "But we trusted that it had been he which should have redeemed Israel: and beside all this, to day is the third day since these things were done."

What this says is "since these things were done".

"to day is the third day since these things were done."

Believe it or not, that is different than:

"the third day since He was crucified".
...

Remember, we have to be persnickety.

 

You have presented no evidence the event where it was said, "to day is the third day since these things were done," was not on that first day of the week.

The Messiah and the 3 days and 3 nights timeframe of Matthew 12:40?

 

What were those "things were done", in their totality, that those folks who were saying this would have been referring to and not just "the crucifixion"? as their reference point of "the third day"?

 

How does this look to you, so far?

We have context that tells us.

The question to ask is,
"What are THESE THINGS that these men referred to?"
- from where this three day period started.

To know the answer we must look back at the previous verses
to see what they were referring to.

In verse 18 Cleopas said to Jesus,

"Are you only sojourning in Jerusalem,
and have not known the things which came to pass there in these days?"

Then in verse 19 Jesus asked him a question, "What things?"

Well this is what we need to know, so look at his reply;
"Concerning Jesus of Nazareth,
who was a prophet powerful in deed and word before God
and all the people."

So the things that "these things" referred to in verse 21
are the things concerning Jesus of Nazareth.

This would include his arrest, trial, crucifixion, death,
the piercing of his side, his removal from the cross,
the anointing of his body, his burial,
and the sealing of the tomb on the following day.
