Looking to Genesis ch. 27, both Esau and Jacob were blessed to compete for royal positions by their father Isaac. Isaac gave Israel a greater blessing than Edom, and thus it is such that we should not abhor Edomites.
I understand Jesus as a messiah-king of Edom, and those who were nobles in medieval Europe all had Edomite genealogies stemming from the Royal House of Troy. Many agree that the followers of Judaism had terrible times then. Things are different now. Already many have said, "This is a good time to be a Jew." I am hoping that the next 1,000yrs brings prosperous Jewish dynasties, like the reign of Solomon and David 3,000yrs ago.
