If the entire book of James is written to "The 12 Tribes scattered abroad" how can they be done away with?

The jest is that they were scattered, but he promised their return in these the last days. They are returning. The Gentiles are first the Jews are last, reversed from previous periods. And many of the people out there do not know they have some of the blood if Israel in their veins. Most are from the tribe if Ef-rem (Ephraim) whos "branches run over the wall" in his blessing by Jacob.
