The problem you fail to grasp is that the people claiming to be descendants of Judah "The Jews" are not physical descendants of Judah. You are unable to work out in the Bible who is who, moreover you contradict the words of Jesus Christ.
Let's continue with Edom, I get it Christians have been brainwashed into believing those people living in Israeli today are Biblical Judahites.
EDOM IS MODERN JEWRY, who says this ? New standard Jewish Encyclopedia 1977, page 586 Jewish Encyclopedia 1904, page 41 Jewish Encyclopedia 1925, Book 13, 5-41
Are you with me now ?
These are not the sort of things that are told by the popular schools of prophecy, because they do not fit in with the "all world" doctrine. But even the Jewish Encyclopedia says modern Jewry is Edom! Let us look from another angle, Edom has always been very jealous and has opposed Israel, even from the time the children of Israel were on their way to inherit the promised land. Edom came out to prevent the passage- Numbers [20]And Edom said vnto him, Thou shalt not passe by me, lest I come out against thee with the sword.19And the children of Israel said vnto him, We will goe by the high-way: and if I and my cattell drinke of thy water, then I will pay for it: I will onely (without doing any thing else) go thorow on my feet.20And he said, Thou shalt not goe thorow. And Edom came out against him with much people, and with a strong hand.21Thus Edom refused to giue Israel passage thorow his border: wherefore Israel turned away from him.
Has anything changed? Who are among the main enemies of Biblical Christianity in the west today? Who was Jesus continually up against when He walked the Holy Land. It was always "The Jews"
Let this quote sink in ~ Encyclopedia Judaica 1971, 6, column 379, "Edom is the eternal enemy of Israel and Judah".
