Semites are peoples who speak Semitic languages; the group includes Arabs, Aramaeans, Jews, and many Ethiopians. In a Biblical sense, Semites are peoples whose ancestry can be traced back to Shem, Noah's eldest son. The ancient Semitic populations were pastoral Nomads who several centuries before the Christian Era were migrating in large numbers from Arabia to Mesopotamia, the coasts of the Mediterranean Sea, and the Nile River delta. Jews and other Semites settled in villages in Judea, southern Palestine.
