Some insist that the modern day Jews are not Israelites at all. It says the true Israelites are European, particularly British, and through them, the Americans. It claims the so-called lost tribes of Israel migrated to this area after Assyria was defeated. But it is well known that the British are descended from the Celts, and that their ancestors were the Cimmerians. A number of ancient sources identify this ethnic group as Biblical Gomer, not as Israel. Two of these sources were from the Assyrian empire. This proves that Cimmeria already existed when Assyria was in power. So this theory cannot possibly be correct.
Further, those in Judea are instructed to flee when they see the abomination of desolation. Zechariah prophesied of the times following this event.
Behold, I will make Jerusalem a cup of drunkenness to all the surrounding peoples, when they lay siege against Judah and Jerusalem. And it shall happen in that day that I will make Jerusalem a very heavy stone for all peoples; all who would heave it away will surely be cut in pieces, though all nations of the earth are gathered against it. (Zechariah 12:2-3)
For I will gather all the nations to battle against Jerusalem; The city shall be taken, The houses rifled, And the women ravished. Half of the city shall go into captivity, But the remnant of the people shall not be cut off from the city. Then the LORD will go forth And fight against those nations, As He fights in the day of battle. (Zechariah 14:2-3)
And it shall come to pass in all the land, Says the LORD, That two-thirds in it shall be cut off and die, But one-third shall be left in it: I will bring the one-third through the fire, Will refine them as silver is refined, And test them as gold is tested. They will call on My name, And I will answer them. I will say, This is My people; And each one will say, The LORD is my God. (Zechariah 13:8-9)
Since these words were written, there has never been a time when siege was laid to Jerusalem, and the Lord came to her rescue. Nor has there ever been a time when half the city was led away captive, but the other half remained there. Nor has there ever been a time when two thirds of those in the land were killed, but one third were saved and restored to faith in the Lord. Thus we see that these prophecies unquestionably refer to the future. But they are about Jerusalem, Judah, and the land. In the last section we saw many specific details proving these prophecies refer to the physical descendants of the ancient nation of Israel. But that is not all they prove. They also prove these prophecies refer to the physical land of Judea (the land now called Israel) and to the physical city of Jerusalem.
We therefore understand that Judah, that is, the real Jews, will be in their ancient homeland when all this happens. Yet the ones who live in this land are not the British or the Americans, but the modern day Jews. Thus we see that this doctrine, which is sometimes called British Israelism, is contrary to both history and scripture.
