The Exodus is the founding myth of Israel, telling how the Israelites were delivered from slavery by their god Yahweh and therefore belong to him through the Mosaic covenant. Spread over the books of Exodus, Leviticus, Numbers, and Deuteronomy, it tells of the events that befell the Israelites following the death of Joseph, their departure from Egypt, and their wanderings in the wilderness, including the revelations at Sinai, up to their arrival at the borders of Canaan.
The exodus narrative is not history in the modern sense, (no archeological evidence has been found to support the historical accuracy of the biblical story) but rather a demonstration of God's acts in history through Israel's bondage, salvation and covenant. It was shaped to its present form in the post-Exilic period, but the traditions behind it are older and can be traced in the writings of the 8th century BCE prophets; it is unclear how far beyond that the traditions might stretch, and their substance, accuracy and date are obscured by centuries of transmission.
The Exodus is central to Judaism, and even today it is recounted daily in Jewish prayers and celebrated in the festival of Passover. In addition, the Exodus has served as an inspiration and model for many non-Jewish groups, from early Protestant settlers fleeing persecution in Europe to African-Americans striving for freedom and civil rights.
