Most Christians are familiar with the prophets Isaiah and Jeremiah, but they are not aware that their message was targeted to Judah, and had nothing to do with Northern Israel.
The split in the kingdom after Solomon’s death separated the tribes into two entirely separate kingdoms with their own kings, prophets, and ultimate destinies under two different conquerors.
The prophets Hosea and Amos were contemporaries of Isaiah, but are seldom quoted or otherwise mentioned. Rather, the prophets to the kingdom of Judah are taught and known among the scattered 10 tribes, then people wonder why the facts don’t seem to fit their functions.
There was yet another significant difference between the kingdoms. Northern Israel’s population migrated when it became evident that the Assyrians had intentions of invasion and avoided slavery for the most part. Only the poorest of the poor farmers and herdsmen were left to be transported into captivity. Judah stayed and a significant portion of them went into slavery. Why?
Judah had gone into poverty as a nation by the time Nebuchadnezzar invaded, and the trade links between Judah and the Phoenicians were long broken. They had no ports of any significance if they had been able to contact the merchant ships. They were trapped in a land that had no doors of escape. Not so with Israel to the north.
Israel and the Phoenicians were so intertwined in trade and intermarried in social order that they had become one people. Jezebel was a Phoenician princess. Those ties put the entire Phoenician fleet at their disposal when the decision was made to migrate out of the land and into other areas, so they used this resource and scattered to the 4 corners of the earth, into every ocean and tributary to every river on the map. The promise to sift them like wheat into every nation on earth was remembered and accomplished.
The two nations are separate and distinct. It is inappropriate for the descendants of the 10 northern tribes to be studying the words of kings and prophets that were never associated with them or their nation. Rather, their appropriate kings and prophets are lost to them, lost along with the knowledge of their true identity.
The scattering, done under the circumstances of a hasty exit had one more effect on the people: They left all of their records and writings behind to be burned by the invading forces. The only available source to reconstruct their history and religion is the ancient writings of their surrounding nations, letters in the archives of Egypt, letters in the archives of Assyria, Babylon, Ionia (not to be confused with Spain, but a separate settlement of people in the south-east of the Spanish peninsula), Ireland, England, and the other ancient sea-port nations.
