Ezekiel 47:23 And it shall come to pass, that in what tribe the stranger sojourneth, there shall ye give him his inheritance, saith the Lord GOD.
God will distribute the land to His people in the millennial kingdom. There will be strangers or aliens living there that are not Jewish. They will be resident aliens. They will be considered native born Israelites. They will be given a portion of land. God will take care of not only His people, Israel, but also those that are believing Gentiles.
God makes provision for all. Not just the chosen people of Israel. God will give the stranger a place!
