According to the finished primary narrative of Genesis through Kings,Israel's origins can be told in a sequence of differentiated stages. InGenesis, the place of Israel in the larger world is defined by bloodrelationship to Abraham, or the lack of any such immediate genealogicalconnection, and the peoples of Israel are explained as tribes with commonancestry under one father, Jacob. By the invitation of Joseph, the entirefamily moves to Egypt during a severe famine, and this change of venue setsthe stage for the second main phase of Israel's origins, a miraculousextraction from slavery to Egypt recounted in the book of Exodus. AlthoughYahweh offers direct entry into a Promised Land, the people are petrified bytheir spies’ report of giants in the land (Numbers 13–14), andthis faithless generation is condemned to wander in the wilderness for fortyyears until they are replaced by their more willing offspring. The finalphase of Israel's origins involves the invasion itself, begun by a sort ofaccidental conquest east of the Jordan River (Numbers 21; Deuteronomy2–3), the prelude to the real thing described in the book of Joshua.After a pair of victories at Jericho and Ai, Israel defeats the assembledkings of southern and northern centers in open field battle (Joshua10–11), and this is the basis for apportionment of the land alongtribal lines.
