Jesus actually sent his disciples to 'THE LOST SHEEP' aka the ten lost tribes that had occupied northern ISRAEL the land since the separation into Judah and Israel.
This happened after the tribes of Ephrain and Manasseh set up Jeroboam on the throne of the Israel the combined country. The tribe of Judah split off to put Rehoboam on a throne of their own country Judah. Ephraim and Manasseh and the other eight tribes named their part Israel later renamed Samaria.
The Assyrians then captured Israel and transported the ten tribes to the area of the Caspian Sea.
This isn't right. I've heard this before, but it turns out its just a theory based on the similarity of the names Samaritan and Sarmatian.
The Assyrians slaughtered the Israelites. The total number of captives they took was recorded on a cylinder by Sargon II commemorating the victory. We still have that relic, and it says only 27,290 persons were taken from Samaria. This is a historically verifiable fact. The prophets in the Bible agree as well, calling Israel "no people" and "dry bones."
The Assyrians filled Israel with Babylonians and other devil-worshipping pagans we call Chaldeans but which were renamed Gentiles or Samaritans like the woman Jesus spoke to at the well.
The Assyrians settled a small group (less than 7000) of "criminals" who were "pardoned" there, as well as an unspecified number of captives from "southern Arabia." According to the same cylinder.
Jesus started preaching but said to the woman who asked him to cure her daughter but Jesus said unto her Matthew 15:24 But he answered and said, I am not sent but unto the lost sheep of the house of Israel.
25 Then came she and worshipped him, saying, Lord, help me. 26 But he answered and said, It is not meet to take the children's bread, and to cast it to dogs.'
He sent his discples to the lost sheep but not the Gentiles of Samaria: Matthew 10:5 These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not: 26 But go rather to the lost sheep of the house of Israel.'
Luke 19:19 seems to indcate that the lost sheep are merely the Judahites but Jesus was actually telling the tax collector that because he believed Jesus was the son of man he could also be counted as a genuine son of Abraham. 19:9 And Jesus said unto him, This day is salvation come to this house, forsomuch as he also is a son of Abraham. 10 For the Son of man is come to seek and to save that which was lost.
In apocalyptic literature, including parts of the Bible, each nation is represented by an animal. The correlations are consistent across all the books. "Sheep" are consistently Israelites. "Dogs" are Canaanites. "Wolves" are Egyptians. And so on and so forth. The audience would have known this.
As for determining who is a genuine son of Abraham, Jesus doctrine is explicit on this point - it should be determined by looking at BEHAVIOR, not genealogies. If we are going to follow his teaching, the question of genealogical descent is pretty much a moot point at best, and a detraction from the truth at worst.
Today's Jews are actually Judahite worshippers of Baal-Moloch under the star flag of Remphan. All are doomed.
While the flag of Israel does have star of Remphan, most of the "Jews" there are atheists and not worshipping anyone at all.
Todays Gentiles are Samaritan-Babylonians and equally doomed.
"Gentiles" just means "nations." It's literally everyone who isn't Jewish. It isn't even a pejorative term in the prophets. God promised to make Abraham a "father of nations," for instance. That's the same thing as a "father of gentiles." Same word (goyim).
Today's Israel is really the trobes of Ephraim, Manasseh, Rueben, Simeon,Napthtali, Gad, Asher, Issacar and Zebulon, Dan. These inhabit England and America with associated territories and former empires.
Now you're way off in left field. This teaching is known as British-Israelism, and was espoused by Herbert Armstrong (late of the cult known as Armstrong-ism), and believed by some other fringe groups, as the Jehovah's Witnesses. It originated in England just a few centuries ago, the evidence for it is extremely scant, and there is no historical attestation for it at all. Even the groups who used to hold to this have moved off the position considerably in light of the historical record of racism
associated with the belief. It really appears that somebody along the way decided that the "chosen nation" must ought to be white-and-go-to-our-church.
