Wrong.
The word "Semitic" means "of Arab origins" and does not mean Jewish, although Hebrew are of Arab origins.
Jews have not always been living in Palestine in significant numbers.
First of all, they did not live there at all until they invaded around 900 BC, and were never the majority.
They were defeated and kicked out by the Babyloniand around 700 BC, again by the Assyrians around 600 BC.
There were almost no Jews there when the Geeks took over aroudn 300 BC
The Romans pretended there was a Jewish country around 150 BC, but it was always fake.
But the Romans kicked out the Jews by 170 AD.
The Crusades wiped out any remaining Jews.
There were no significant Jewish population in Palestine for thousands of years.
Much larger Jewish population were in Spain, Egypt, Russia, Poland, etc.
And no land should be based on religion.
That is against every single legal principle.
