Hebrew Heraldry - The Royal Jewish Bloodline: A Brief History of the Jews and Jewish Symbols

The Jewish royal family in Roman times was descended from priests, and not from David. The starting point of this story is the fact that Josephus Flavius, and with him the whole Judaic priestly line, descended directly from Moses.

Yet, according to the universally recognized and accepted tradition, all the priests descended from Moses's brother Aaron. It is a tradition that was born at the time of Ezra--and because of the works of Ezra. Since then, it has been continually reasserted with force and conviction, to the point of becoming an unquestioned truth that nobody has ever doubted, but it's a truth that is easy to disprove based on the information provided by the Bible.
