modern "jews" are descended from mongol-turk separatists who came into being primarily to exploit a loophole in roman law during 700 a.d. khazarians, as their often referred. their religion was based off of part of the pre-existing christian texts - not the other way around. (the original early monothiests of the bible were nomadic and didn't have the ability to make books. rome, on the other hand, had excellent record keeping and libraries necessary to preserve scripture.)  after 700 ad, that's when these new jews propagated and created the culture and identity of judaism. they are larpers essentially - and any similarity they have with the jews as they're described in the bible is a result of this larping activity being reinforced through the centuries. the jews referenced in the bible, such as the nazarean greeks, were not a single unified group but a loosely defined group with wildly different ideas about god and the awaited messiah. nearly 100% of these biblical jews converted, interbred with early christians, or died out. we know this because virtually every "jew" in israel is descended from the 700 ad group. amazingly enough, jesus himself spoke of the distinction between himself and his followers and those who could claim the moniker of "jews" in the future. jesus was an insightful and smart guy- to say the very least. hope that clears up some confusion.
