Because I had trouble understanding the what was meant by the following words: -
It was all as meaningless as a when a turkey is gobbling. The quoted portion of your OP needs explaining in simpler terms so that us poor readers can understand the point of the question otherwise it is a pointless collection of words. You may know what you are talking about, but us poor plebs, like me, cannot get our laughing matter around it. Know what I mean?
I know what you mean. I'll put it another way, Read John only. Read from 13:1 to 31, that's in the night before "the Lord was betrayed" 1Corinthians 11:23.
You do agree? How not?
Fine. Chapter 14,15 and 16 are "words Jesus spake" 16:1 and closed with his Gethsemane prayer in chapter 17, That Selfsame Night?
Do you agree? I cannot see how not?
So, That Selfsame Night still, "when Jesus had spoken these words, He went forth with his disciples over the Dark Brook (Cedron) and Judas also who betrayed Him" That Selfsame Night?!
That Selfsame Night indeed!
And you know the story further, How that Jesus was taken to Trial "That Selfsame Night Whole Night" still!
Then: "Six o'clock in the morning" Jesus was brought out from the governor Pilate's house and setting out for Golgotha, began to carry his cross, That Selfsame Day sunrise!
True or false? I see you say, Of course, true! Of course yes, True!
Then what happened next, That Selfsame Day?
They Crucified Jesus. We also know that they crucified Him 9 o'clock That Selfsame Day, and that at noon there came darkness over all the land That Selfsame Day, daylight time! Until 3 p.m. we know, 3 p.m. That Selfsame Day and Jesus called out with a Great Voice and gave the ghost.
Where are you reading the Gospel of John, now?
You are reading verse 30!
So, everything you have thus far read, was what happened on "The Preparation OF THE PASSOVER" you have read about already back there in John 13:1 In Substance That Selfsame Day Whole Day "when they always had to KILL the passover" which was the fourteenth day of the First Month for Israel.
Is this true, that is, is this "according to the Scriptures", viz., the Gospel of John?
YES OR NO!?
Let us now read the other three Gospels at the same place in history and Scripture ...
