The Bible was written 2000 years ago by we know not whom and with no corroboratotry contemporary accounts. However, since reliable records began the jewish race was never more than a small proportion of the Palestinian population. If the world as a whole were to take the Jewish example and religions or ethnic groups laid claim to lands that were listed as belonging to them in the Bible then the whole world would be in the same intractable chaos that we see in Palestine. You can not use the Bible as a Land Register.
