The Pharisees were a political group more than an ethnic one, and while they were pretty much wiped out with the rest of the Hebraic Jews in AD 70, their traditions are still strong in modern Judaism. Their survivors these days are the Sephardic Jews. But ethnically they were no relation to the Khazars. The Khazars were a people who became prominent about 600 AD in the region north of Turkey, now southern Russia. They became Jews because they were pressed by the retreating Christians and the advancing Muslim conquerors. It was a practical choice on their part because they could trade with both, and we should be glad they did it because it wasvsomething of a roadblock to the spread of Islam to the northeast of Europe. And the idea that a modern cabal is dominated by the descendents of the Khazars is some generalization about Rothschilds. They may very well not have been the most religious of peoples, that only makes it less likely they are following any religious practice, not devoting themselves to the Osiris-Isis-Horus cult.
