This does not prove your point. Everyone who rejects Christ, jew or gentile will be cast out..
The kingdom is from the Euphrates river to the Nile river.That is the promised land. Thats why the people of Israel who worship the beast and reject Christ are exiled beyond Damascus.Damascus is within the borders of the promised land.
Amos 5
“Did you bring me sacrifices and offerings
forty years in the wilderness, people of Israel?
26 You have lifted up the shrine of your king,
the pedestal of your idols,
the star of your god[b]—
which you made for yourselves.
27 Therefore I will send you into exile beyond Damascus,”
says the Lord, whose name is God Almighty.
