Based on what? The descendants of Ham are Biblically recorded as the “swarthy” people. The Messiah was a Semite (of Shem) in all his generations.
Well, it was a “mixed multitude” that came out of Eqypt, so there was a bit of everyone from the area.
But if you look at the ancient freezes and whatnot you can easily view in Israel today, the Jewish people looked pretty much like they do today, but slightly less European.
It was like arabs with curly hair, as my un-PC wife explained it.
