That's true, becauyse that's not my agenda. Sadly, it is the emergent obligation when confronted with false claims and lies.
So Rashi was a modern myth maker? Got it.
מסר עצמו בכל מיני מות שגזר עליו על לא רצה לקבל עליו כפירה לעשות רעה ולחמוס חמס ככל הגוים אשר היה גר ביניהם
You have two questions. The first asks about why God feels a need to do something. That's unanswerable. If you think you can answer it then you are more arrogant than I ever thought, deciding that you know why God decided to do something. The second asks about why something isn't a prophecy about someone's death in particular (if you knew Hebrew, you'd know that "Yeshua" isn't the name). I could show how other required elements of that chapter invalidate jesus as claimant. I could show how this prophecy has applied to Jews during the course of history. I could show how those who see this also as a reference to the Jewish messiah figure understand how this applies (וְיִמְסַר יַת רַשִׁיעַיָא לְגֵהִנָם וְיַת עֲתִּירֵי נִכְסַיָא דַאֲנַסוּ בְּמוֹתָא דְאָבַדְנָא בְּדִיל דְלָא יִתְקַיְמוּן עָבְדֵי חֶטְאָה וְלָא יְמַלְלוּן נִכְלִין בְּפוּמְהוֹן)
No, it's not arrogance. There are no wasted statements in Tanakh. God 100% of the time gives consistent, relevant advice--for hearers then and now. You are ducking and dodging the simple contrast:
* Christians recognize the statements from Isaiah 53 as obvious prophecy about King Messiah Jesus
* Non-Messianic Jews go to lengths to avoid discussing Jesus as the main focus of Tanakh prophecy, for example, saying "It was [mysteriously] important for God to take time in Tanakh to tell Jewish people that other Jewish people will die near rich persons, still others, die near sinners."
You further claim that *other* parts of Isaiah 52-53 refute the Lord Jesus Christ's fulfillment of prophecy, yet you won't admit the obvious issue with the above. Put differently, since you have no valid, insightful, spiritual or logical answer to the prophecies of verse 9, so you are excited to go to ground where you are more confident in your anti-Jesus apologetics. Why should we bother when the answers are so simple, per the below, concerning the whole passage?
The Lord has made bare His holy arm
In the eyes of all the nations;
And all the ends of the earth shall see
The salvation of our God.
[Jesus stripped bare and witnessed internationally]
13 Behold, My Servant shall deal prudently;
He shall be exalted and extolled and be very high.
[Jesus lifted on the cross, then lifted internationally by billions of Gentiles]
14 Just as many were astonished at you,
So His visage was marred more than any man,
And His form more than the sons of men;
[Jesus mocked, beaten nearly beyond recognition, a sacrificed lamb]
15 So shall He sprinkle many nations.
Kings shall shut their mouths at Him;
For what had not been told them they shall see,
And what they had not heard they shall consider.
[Gentiles brought to Tanakh, salvation and the gospel from Acts and onward]
Who has believed our report?
And to whom has the arm of the Lord been revealed?
[Jews despise their own Messiah, revealed first to Jews . . . then to the nations]
2 For He shall grow up before Him as a tender plant,
And as a root out of dry ground.
[Prophesied branch from the felled stump of the Davidic kings, a tender child grown to a man]
He has no form or comeliness;
And when we see Him,
There is no beauty that we should desire Him.
[Not a handsome man, Judas had to identify Him with a kiss, beaten badly for our sin]
3 He is despised and rejected by men,
A Man of sorrows and acquainted with grief.
[Grieved over Jerusalem and His Jewish people, despised and mocked for us]
And we hid, as it were, our faces from Him;
He was despised, and we did not esteem Him.
[Disciples fled, the rabbis mocked Him on His cross]
4 Surely He has borne our griefs
And carried our sorrows;
Yet we esteemed Him stricken,
Smitten by God, and afflicted.
[He brings believers joy through His redemption]
5 But He was wounded for our transgressions,
He was bruised for our iniquities;
[Literally wounded and bruised for our sin]
The chastisement for our peace was upon Him,
And by His stripes we are healed.
[He is our shalom and a miracle cure, He also heals people spiritually/holistically where they are not cured]
6 All we like sheep have gone astray;
We have turned, every one, to his own way;
And the Lord has laid on Him the iniquity of us all.
[Humans sin and turn from God "naturally", Jews reject the missing Temple sacrifices for mitzvot and prayer and the way of salvation NOT found in Tanakh which is to TRUST GOD for salvation]
7 He was oppressed and He was afflicted,
Yet He opened not His mouth;
He was led as a lamb to the slaughter,
And as a sheep before its shearers is silent,
So He opened not His mouth.
[Jesus refused to defend Himself at trial, but was ultimately rejected for answering when adjured under oath that HE IS GOD]
8 He was taken from prison and from judgment,
And who will declare His generation?
For He was cut off from the land of the living;
For the transgressions of My people He was stricken.
[Held at Caiaphas's home, we preached in His Name, He died for Israel first]
9 And they made His grave with the wicked—
But with the rich at His death,
Because He had done no violence,
Nor was any deceit in His mouth.
[He died for the crime of being KING OF ISRAEL, died amongst thieves, was honored in an unused, wealthy Pharisee's tomb]
10 Yet it pleased the Lord to bruise Him;
He has put Him to grief.
When You make His soul an offering for sin,
He shall see His seed, He shall prolong His days,
And the pleasure of the Lord shall prosper in His hand.
[God willed His death, He shall RISE FROM THE DEAD, FOR ETERNAL LIFE]
11 He shall see the labor of His soul, and be satisfied.
By His knowledge My righteous Servant shall justify many,
For He shall bear their iniquities.
[From one sin of Adam man is ruined, for billions of sins, Messiah died and justified many]
12 Therefore I will divide Him a portion with the great,
And He shall divide the spoil with the strong,
Because He poured out His soul unto death,
And He was numbered with the transgressors,
And He bore the sin of many,
And made intercession for the transgressors.
[His Name is great and He is the most influential person ever/still, though He isn't even on Earth! PRAISE YESHUA MELEKH MOSHIACH!]
