I watched most of it. He makes a some major assumptions. Rather pathetic, really. What is the point? Why this horrible drive to prove that "I am really Jewish"?
There is one reasonable assumption which is the average time between generations, the rest is straight forward maths and statistics.
The reason I am proving that we are all from one of the tribes of Jacob is because most Christians read:
Revelation 7:3
“Do not harm the land or the sea or the trees until we put a seal on the foreheads of the servants of our God.” 4Then I heard the number of those who were sealed: 144,000 from all the tribes of Israel."
And think that some how you have to be Jewish to be in the 144,000 but there are two major wrong assumptions they make by doing so:
1. Jews only come from the tribe of Judah and not the other 11 tribes.
But putting this mistake to one side there is the much bigger mistake:
2. Only Christian's can be part of God's Eternal Kingdom, Jews and all the other so called tribes (that don't exist genetically speaking anyway) will all go to Hell.
Revelations is clear that the 144,000 will rule with Christ on Earth during His Millennial reign:
Revelation 20
4I saw thrones on which were seated those who had been given authority to judge. And I saw the souls of those who had been beheaded because of their testimony about Jesus and because of the word of God. They had not worshipped the beast or its image and had not received its mark on their foreheads or their hands. They came to life and reigned with Christ a thousand years. 5(The rest of the dead did not come to life until the thousand years were ended.) This is the first resurrection. 6Blessed and holy are those who share in the first resurrection. The second death has no power over them, but they will be priests of God and of Christ and will reign with him for a thousand years.
