By the time of Christ, they'd had >200 years exposure to the Greeks. From what I remember of discussions with Alamo Girl on the book of Enoch, c. 200 BC, it showed Hellenistic influences.
I read somewhere, maybe Will Durant, that when the Greeks and Jews first encountered each other in a big way, during the time of Alexander, each culture was fascinated by the other. Many Jews adoped Hellenic culture, and (according to Durant) the Hellenes wrote that they had discovered a nation of philosophers. Clearly (aside from theology) the Greeks were way ahead at the time of the cultural encounter. No nation ever had a collection of people like Aristotle, Euclid, Archemedes, etc. The US came close, during the Revolutionary period.
