No that's not it...
The Jews are the Israelites, God's chosen people and they are currently in the land God gave them as an everlasting possession...pretty cool!
No doubt some rejected Him for hat reason, the Pharisees and teachers of the law didn't though. Anyway, maybe hey should have remembered Isaiah 53? I don't know but I'm glad to have been grafted in anyway, God turned what they did for good for me and you and everyone else who believes
Well some of them are still scattered, living in other countries. Why, 5,000 of them living in France and hating the anti-semitism just went to go live in Israel...so they are still coming. God's still bringing his people back to the land He promised them!
Maybe some of them don't think they are the real Jews, and maybe hey aren't but most of them there are the real Jews. Hitler made sure to round up all the authentic ones for us and tried to gas them all, but that didn't happen and they went back to their homeland.
