The Torah wasn't written by the Gnostics or for the Gnostics. They had no idea of its existence. They were Hellenists, Greeks. The Torah was written by the Jews to teach them to observe the Mosaic Law. It wasn't written for the Gentiles.
While I lived for a few years with a JW aunt after my family dissolved, I was born and raised Jewish and continue to be to this day. One of the things my Jewish education has afforded me is to know the difference between when the Gnostics came on the scene and when the Levitical priesthood did, which was centuries before.
The Kohen line, otherwise known as the Levites, were influencing the people of the Levant to Judahite religion long before Babylon came and drove the people away in chains. The Yahveh God may not have been the only God the Kohens promoted at the time, but eventually they developed their trademark monotheism that Judaism became known for. Some time before 586 B.C E. these priests and their scribes (and their prophets) were a group, even though they didn't resemble the Bible tales exactly the way they are portrayed in the narratives.
The Gnostics, who are Gentiles of Greek origin, did not come onto the scene until circa 300 B.C.E., maybe 400, but that is stretching it. Most scholars actually put their arrival at about 200 B.C.E.. But the ones who studied the Gnostics who studied the Jewish texts? Those are the generally known as the Marcionists.
Marcion of Sinope, the 2nd-century (C.E.) Christian bishop who went rogue by creating (get this) the very first Biblical canon (as the Church Fathers did not believe the Christian congregation needed an official Biblical canon), made things worse by threatening the Church with Gnosticism and the teaching that salvation came to a select group that could glean enough gnosis from holy writings and become demi-gods like Jesus. (The Church countered this with the teaching that salvation was "katholicos" or "universal"--catholic, open to all who had faith in the gospel, whether they read it from Scripture or merely heard it preached from another Christian. And the Church thereby set to creating an official list of canonical writings, excommunicating the Marcionists.)
Plato was born in 428 BCE. He did not read, study or teach the Hebrew text. In fact, there is no textual evidence which shows any early Greek philosopher (from Thales to Epicurus) quoting or commenting on The Old Testament. Both Phythagoras and Plato were reported by some to have traveled to Israel and the greater Middle East but there is no reliable textual evidence which proves this.
I am Jewish. I know the interpretation of my own people's culture. The reason for the narratives and the characters of Eve and Balaam are placed in the Torah is to teach Law--this is not a book of "History." This is the Law, a book of binding commands. Any narratives within the Law teach Jews how to apply the Law by illustration, not history or a bedtime story. These narratives do not teach Greeks wisdom. They are designed to teach my people how to apply the Mosaic Law. Five books of Law. Not history. Not tales of wisdom. Law. Torah.
In Judaism, God is not spirit or mind. God is Ineffable.
