Lost Ten Tribes in the West according to the Prophets and History
See Origin (2nd Edition).
The Beginning
The People of Israel descend from the Patriarchs Abraham, Isaac, and Jacob. The name Israel was given to Jacob (Genesis 32:28, 35:10). There were Twelve sons of Israel who became the forefathers of Twelve Tribes. The Tribe of Joseph was split into two and is usually counted as two separate tribes, Ephraim and Manasseh. Joseph and after Joseph, Ephraim, was given the right of the first-born whereas the leadership was to come from Judah
1-Chronicles (TCT) 5:
1 AND THE SONS OF REUBEN, THE FIRSTBORN OF ISRAEL, FOR HE WAS THE FIRSTBORN, BUT WHEN HE DEFILED HIS FATHER'S BED, HIS BIRTHRIGHT WAS GIVEN TO THE SONS OF JOSEPH THE SON OF ISRAEL, BUT NOT TO BE RECKONED IN THE GENEALOGY AS FIRSTBORN.
Israel and his twelve sons descended into Egypt where their descendants were enslaved. Under Moses the Israelites came out of Egypt. They entered the Promised Land of Canaan and conquered it. King David, from the Tribe of Judah, established the capital at Jerusalem within which his son Solomon built the Temple. In the reign of King Rehoboam, son of Solomon, ten of the northern most tribes seceded and formed their own kingdom (1-Kings 12; 20-23), which was referred to as Israel (e.g. Hosea 5: 5). The remaining Tribes, Judah and Benjamin, who remained faithful to the House of David were called Judah. The modern Jews are mostly descended from former inhabitants of the Kingdom of Judah though many individuals from the northern seceding tribes also made their way south,
e.g.
2-Chronicles (NASB) 15:
9 AND HE [KING ASA OF JUDAH] GATHERED ALL JUDAH AND BENJAMIN, AND THOSE FROM EPHRAIM, MANASSEH, AND SIMEON WHO RESIDED WITH THEM, FOR MANY DEFECTED TO HIM FROM ISRAEL WHEN THEY SAW THAT THE LORD HIS GOD WAS WITH HIM.
In the course of time, these too became part of the Jewish nation. The two kingdoms of 'Judah' and 'Israel' continued to exist side by side for more than one hundred and fifty years. At times they co-operated and on other occasions they were hostile to each other. Eventually the Assyrians conquered the northern kingdom and exiled all of its inhabitants.
They disappeared to history. They are known as the Lost Ten Tribes of Israel.
