Anti Semitism in Christianity

Anti semitism has always existed in ancient christianity. Heraclius was alive when the moslems conquered jerusalem. He said, they will rule this land under my feet in less than seven years. Eventually, it wasn't until 300 years from now that he says that what he's saying is true. All of this goes to stolexandria, within a million miles ofJerusalem and then on into syria for another 300 years.
