The concept of a God-man savior preceded the pagan counterfeits, when God revealed the woman (no mention of a man, since God is His Father) would give birth to One who would suffer and die but would be resurrected and crush the snake and defeat his purpose against mankind (Gen. 3:15).

The suffering servant of Isaiah 53 is the Jewish nation.

Many Jewish people are self-righteous enough to consider themselves worthy of atoning for mankind, but only One from the Jewish nation - Yeshua - qualifies, having died and been resurrected, atoning for many, seeing his spiritual descendants, since He is alive. How else could someone who died - as the The Suffering Servant did (Israel is still alive - remember Am Israel Chai? The Nation/People of Israel lives), see the travail of His soul was well worth the sacrifice?

Isaiah 53:

1 "Who has believed our report? (most of Judah and Israel - professing Christianity - haven't believed the Report and either reject Yeshua or accept a Gentilized version)

And to whom has the arm of the LORD been revealed?

2 For He shall grow up before Him as a tender plant,

And as a root out of dry ground.

He has no form or comeliness;

And when we see Him,

There is no beauty that we should desire Him.

3 He is despised and rejected by men,

A Man (not a nation, a man) of sorrows and acquainted with grief.

And we (collective Israel, especially Judah) hid, as it were, our faces from Him;

He (one man) was despised, and we (Israel/Judah) did not esteem Him.

4 Surely He has borne our griefs

And carried our sorrows;

Yet we (collective Israel/Judah) esteemed Him stricken,

Smitten by God, and afflicted (and curse His holy Name).

5 But He was wounded for our (Israel/Judah) transgressions,

He was bruised for our iniquities;

The chastisement for our peace was upon Him,

And by His stripes we (Israel/Judah) are healed.

6 All we (Israel/Judah) 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.

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.

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 (just as Daniel foresaw He went "missing");

For the transgressions of My people (the sins of Israel and Judah - they can't be their own savior) He was stricken.

9 And they made His grave with the wicked (Am Yisrael Chai - Israel has never died or God's Word would have been broken to the Fathers)
