Jesus does provide us with the knowledge of Elohim and eternal life is knowing the Son and the Father. (John 17:3), but how does the servant of Isa 53 "bear their iniquities"?
There's more context about the righteous servant in Psalm 35. The false accusations against him relate to the endorsement of Rome, so the iniquity would relate to the Roman church using him as part of their doctrine.
False witnesses did rise up; they laid to my charge [things] that I knew not.
Psalms 35:11
Let them shout for joy, and be glad, that favour my righteous cause: yea, let them say continually, Let YHWH be magnified, which hath pleasure in the prosperity of his servant.
Psalms 35:27
And whosoever will be chief among you, let him be your
servant:
Even as the Son of man came not to be ministered unto, but to minister, and to give his life a
ransom for many.
Matthew 20:27-28
That has nothing to do with Jesus but shows what might happen in society, it would ransom good people with worthless people.
It relates to Jesus because of the ransom, the lion, and the saviour:
I will ransom them from the power of the grave; I will redeem them from death: O death, I will be thy plagues; O grave, I will be thy destruction: repentance shall be hid from mine eyes.
Hosea 13:14
Therefore I will be unto them as a
lion: as a leopard by the way will I observe [them]:
Hosea 13:7
Yet I [am] YHWH thy Elah from the land of Egypt, and thou shalt know no god but me: for [there is] no
saviour beside me.
Hosea 13:4
For I [will be] unto Ephraim as a
lion, and as a young lion to the house of Judah: I, [even] I, will tear and go away; I will take away, and none shall rescue [him].
Hosea 5:14
After two days will he revive us: in the third day he will raise us up, and we shall live in his sight.
Hosea 6:2
For I desired mercy, and not sacrifice; and the knowledge of Elohim more than burnt offerings.
Hosea 6:6
It connects to the fulfilment of prophecy:
Men [and] brethren, this scripture must needs have been fulfilled, which the Holy Ghost by the mouth of David spake before concerning Judas, which was guide to them that took Jesus.
Acts 1:16 -> Psalm 69, 109
But [this cometh to pass], that the word might be fulfilled that is written in their law, They hated me without a cause.
John 15:25 -> Psalm 69, 109, 35
