Yes, but if you’re looking for how “stranger” or “foreigner” is construed in the Old Testament, and how it would have been interpreted by Jesus and his Jewish disciples, then the word is used almost by definition to distinguish the non-Jew from the Jew. The writer of Hebrews (who comes later of course) gets it: all are strangers on the earth, Jew and Gentile alike, who “desire a better country, that is a heavenly one.”
