Read the book of Esther. All of Israel in the many dispersions under Assyria, Syria or Chaldea are referred to as Jews since Persia controlled the entire middle east including Greece and Egypt. Ahaseurus’ edict took days to get to the farthest part of the kingdom so they extended the time for retribution. It was not just Judah, Benjamin and Levi that they were looking for but all of Israel in exile and they were called Jews.
Apollos born in Alexandria was called a Jew. Aquilla born in Pontus was a Jew. Sceva born in Ephesus was a Jew as were the vagabonds. John calls the Passover and the feast of tabernacles “Jewish” feast and the religion of the temple and synagogues, “Jewish”. It is utter nonsense to make any difference between the tribes in the new covenant since their is no distinction between Jew and gentile until the end times when god makes a differentiation by calling out 12,000 from each tribe of Israel.
Golly, maybe I wasn't wrong.
