When prophecies like Jeremiah 32 and Ezekiel 16 were foretelling the coming Babylonian Captivity of Jerusalem, they compared and contrasted it to the Assyrian Captivity of Samaria. The thing I note about this is that Judah ultimately had two captivities and returns, while Samaria has thus far had one Captivity and not yet a return.
Meanwhile I also feel many difficult to fully understand Prophecies are implying a conflict between Ephraim and Judah in the End Times. From Isaiah 28, (and possibly Isaiah 7-11 which may or may not have Eschatological significance). And Jeremiah 4, and Zechariah 9-11. Like how they were often at war during the divided Kingdom.
Which is a problem for how Two House Theology and British Israelism like to see the Eschatological role of Ephraim. I should also point out that Mormonism teaches a form of Two House Theology.
I'm not a Dispensationalist as that is usually defined, I agree that The Church is grafted into Israel. But we're not grafted into a specific Tribe, Ezekiel 37 says Joseph and Judah both have companions joined to them.
Now people might ask, if the "Lost Tribes" returning is a part of the End Times, where is it in Revelation?
Well it's in Chapter 16, in the Sixth Bowl of God's Wrath. The Euphrates River is dried up to make way for the Kings of the East, East of the Euphrates is where Assyria first took them. But it also describes people coming from all four corners of the Earth, just as Israel was ultimately scattered to all four corners. And they are gathered at Megiddo, Northern Kingdom territory, in the valley of Jezreel which had been one of their capitals.
I think it's possible part of the point of The Millennium is so the Northern Kingdom can have a second Captivity.
Chris White talks about reasons that the Antichrist could resemble the Rabbinic expected Messiah Ben-Joseph, an idea that some Hebraic style Christians have also accepted. But does so leaving the Lost Tribes aspect of that doctrine completely out of it.
I've been talking a lot about The Antichrist possibly ruling from Egypt. How can that and a false Messiah Ben-Joseph claimant go together?
Well between lots of maps online confusing the Brook of Egypt with The Nile, thus expanding Israel's rightful borders to include much of Egypt. And fringe history theories hijacking legit Revised Chronology research to say many Kings of Israel and Judah were really Pharaohs of Egypt. And people trying to claim The Great Pyramid was built to honor Yahuah. And my arguments that some nations believed to be of the Lost Tribes may really be of Exiled Egyptians (or perhaps both). And Hosea foretelling that Ephraim would return to Egypt. And that Jeroboam was a vassal of Shishak. And Leviticus 24 talks about a Blasphemous Israelite who's mother was Danite and Father was an Egyptian There is a lot to work with.
But also that Joseph himself, viewed as the first type of Messiah Ben-Joseph, was essentially placed Second in Command of Egypt by Pharaoh. I think there are a lot of pieces to this puzzle I'm still trying to put together. And Joshua 10:41 says Joshua conquered all the way to Goshen. Either that's a different Goshen, or he conquered the same land they had lived in as slaves. Whichever answer is true, a Messiah Ben-Joseph wanna be claiming to b a new Joshua could well use the latter interpretation.
