John 18:28 says;
Then they led Jesus away from Caiaphas into the Praetorium. By now it was early morning, and the Jews did not enter the Praetorium, to avoid being defiled and unable to eat the Passover.
The only defilement I can think of is contact with the dead that would render a Jew unable to partake of the Korban Pesach.
The background for this is discussed in Numbers 9:6-14.
The process for cleansing is discussed in Numbers 19, and requires 7 days to be cleansed with the waters for the purification of sin.
So the "lamb" was defiled. Does this sound like a good sacrifice?
It happened as it is written:
Isaiah 52:14Just as many were appalled at Him—
His appearance was disfigured beyond that of any man,
and His form was marred beyond human likeness—
15so He will sprinkle many nations.
Kings will shut their mouths because of Him.
For they will see what they have not been told,
and they will understand what they have not heard.
53:1Who has believed our message?
And to whom has the arm of the LORD been revealed?
This is a great question, isn't it? Certainly not you.
2He grew up before Him like a tender shoot,
and like a root out of dry ground.
He had no stately form or majesty to attract us,
no beauty that we should desire Him.
3He was despised and rejected by men,
Still is
a man of sorrows, acquainted with grief.
Like one from whom men hide their faces,
He was despised, and we esteemed Him not.
4Surely He took on our infirmities
and carried our sorrows;
yet we considered Him stricken by God,
struck down and afflicted.
Yep.
5But He was pierced for our transgressions,
He was crushed for our iniquities;
the punishment that brought us peace was upon Him,
and by His stripes we are healed.
6We all like sheep have gone astray,
each one has turned to his own way;
But, according to you...not all. You're not doing what seems right in your own eyes.
and the LORD has laid upon Him
the iniquity of us all.
Who needs a redeemer?
7He was oppressed and afflicted,
yet He did not open His mouth.
He was led like a lamb to the slaughter,
That's what you're referring to.
and as a sheep before her shearers is silent,
so He did not open His mouth.
8By oppression and judgment He was taken away,
and who can recount His descendants?
For He was cut off from the land of the living;
He was stricken for the transgression of My people.
And this explains it all...the why is here.
9He was assigned a grave with the wicked,
and with a rich man in His death,
although He had done no violence,
nor was any deceit in His mouth.f
10Yet it was the LORD’s will to crush Him
and to cause Him to suffer;
and when His soul is made a guilt offering,
How did that work? The soul is in the blood...By the shedding of His blood, we were redeemed.
He will see His offspring, He will prolong His days,
and the good pleasure of the LORD will prosper in His hand.
11After the anguish of His soul,
He will see the light of lifeh and be satisfied.
By His knowledge My righteous Servant will justify many,
and He will bear their iniquities.
12Therefore I will allot Him a portion with the great,i
and He will divide the spoils with the strong,j
because He has poured out His life unto death,
and He was numbered with the transgressors.
That's what you're trying to do with your post. You continue to number Him with the transgressors
Yet He bore the sin of many
and made intercession for the transgressors.
And this is what you need to know...He continues to make intercession for you.
