JJ, you are partially, but not totally correct. Palestinians are not descendants of Hebrew tribes. They descend from Arab, or Palestinian tribes. When Joshua led the 12 tribes across the river Jordan into Canaan, also known at that time as Palestine, the land was occupied: guess by whom? They were semite tribes, Hittites, Amorites and Jebusites. They weren't called Arabs then, and the Israelites weren't called Jews. Those names weren't known yet. But, according to the New York University School of Medicine, and the National Academy of Sciences, Middle East Jews and Palestinian, Lebanese and Syrian men have the same genetic signature, different from any other non-Jews in the world. Some of those same tribes, and the Canaanites also occupied Judea and Samaria. There are notable historians who maintain Palestinians are direct descendant from the Jebusites. If that is so, and, of course, there is controversy, the fore bearers of Palestinians built Jerusalem.
