Read this: Jews originated as a national and religious group in the Middle East during the second millennium BCE, in the part of the Levant known as the Land of Israel. The Merneptah Stele appears to confirm the existence of a people of Israel, associated with the god El, somewhere in Canaan as far back as the 13th century BCE. The Israelites, as an outgrowth of the Canaanite population, consolidated their hold with the emergence of the Kingdom of Israel, and the Kingdom of Judah. Some consider that these Canaanite sedentary Israelites melded with incoming nomadic groups known as 'Hebrews'. Though few sources in the Bible mention the exilic periods in detail, the experience of diaspora life, from the Ancient Egyptian rule over the Levant, to Assyrian Captivity and Exile, to Babylonian Captivity and Exile, to Seleucid Imperial rule, to the Roman occupation, and the historical relations between Israelites and the homeland, became a major feature of Jewish history, identity and memory.
