Study Jewish theology and you will find that they do not believe man needs to be redeemed/saved. The particular verse in Job in your English translation of the Hebrew OT is an abbreviated one -- leaving out some crucial details to wit (a) the Holy One was about to help Job for his (b) present sufferings.
Your version says something completely different: it changes the Holy One to a "redeemer" and also implies that Job's sufferings will be removed in the "latter day" (other versions hint at the distant future even the end of times).
This difference clearly shows how various man-chosen variations of the Bible lead one to read and "believe" different things. The Septuagint was written two hundred years before Christ for Alexandrian Jews, translated from the Hebrew original by 72 rabbis. The Gospels quote from the Septuagint in over 95% of the cases. I place my confidence in them. You place your confidence in a text that was redacted by rabbinical Judaism that rejected Christianity.
Interesting. Moses was a savior, Joseph was a savior, and Jesus is the Savior.
2Sa 22:3 2Ki 13:5
(And the LORD gave Israel a saviour, so that they went out from under the hand of the Syrians: and the children of Israel dwelt in their tents, as beforetime
Ps 106:21
They forgat God their saviour, which had done great things in Egypt;
Isa 19:20
And it shall be for a sign and for a witness unto the LORD of hosts in the land of Egypt: for they shall cry unto the LORD because of the oppressors, and he shall send them a saviour, and a great one, and he shall deliver them.
Isa 43:3
For I am the LORD thy God, the Holy One of Israel, thy Saviour: I gave Egypt for thy ransom, Ethiopia and Seba for thee.
Isa 43:11
I, even I, am the LORD; and beside me there is no saviour.
Whether it was saving them, preserving them or delivering them, God is their Saviour. Several times, Israel came close to disappearing.
In fact, the Plan of Salvation seems to be the central message of the whole bible from what I can see.
We even have Boaz, as kinsman redeemer saving Ruth, without whom, there would be no David.
Torah has been unchanged for 6 thousand years, and she is the Word of God. The beautiful, lovely, unspoiled Word of God. You are the one who needs to study Hebrew theology.
