Many on this forum are quick to point out that the new covenant promise was only for the house of Judah and the house of Israel but can never come to terms with the fact that only the house of Judah remained in the 1st century. All the disciples of Christ were most likely from Judah or Benjamin aka the house of Judah. Jesus was from Judah. Paul was from Benjamin. The Samaritans who were some of the remnants of the house of Israel or the ten northern tribes were rejected by the Jews as a mixed people. Now there were a few remnants of the house of Israel like the few Levites who were still in charge of the temple and a solitary Anna from the tribe of Ashur but as for full functioning tribes the ten were lost to history.
The ten northern tribes or the house of Israel were lost to history 2000 years ago so the dispensational notions of God fulfilling his promise to ethnic tribes in the future are bogus and without merit. God does not deal in worthless genealogies anymore. Those that have faith are accepted by him Jew and Gentile alike. Paul quotes the prophet Hosea in Romans 9 and applies it to the Gentiles indicating that they were brought in to fill the fallen ranks - Even us, whom he hath called, not of the Jews only, but also of the Gentiles? As he saith also in Osee, I will call them my people, which were not my people; and her beloved, which was not beloved. And it shall come to pass, that in the place where it was said unto them, Ye are not my people; there shall they be called the children of the living God. Rom. 9:24-26
