Yep, in 586BC, Nebuchannezzer(sp?) took Judah Captive. They lost their law, their Temple and their GOD (Jer 3:8)
So they translated the written law into Aramaic and also created the Halakah, Talmud, the oral law which can't be written down. So a bunch of Rabbi's, not descendants of Aaron, created the oral law to let the Rabbi's give their "opinions."
This is why Christ was angry with these Rabbi's of his time. it is the synagogue of satan.
