Exodus and conquest
According to biblical tradition, the clan migrated to Egypt because of a famine in the land of Canaan, were later enslaved and oppressed, and finally escaped from Egypt to the desert east of the Isthmus of Suez under a remarkable leader, Moses. The account—a proclamation, celebration, and commemoration of the event—is replete with legendary elements, but present-day scholars tend to believe that behind the legends there is a solid core of fact; namely, that Hebrew slaves who built the fortified cities of Pithom and Rameses somehow fled from Egypt, probably in the 13th century bce, under a great leader (see also Moses). A stele (inscribed stone pillar) of the pharaoh Merneptah of that time in which he claims to have destroyed Israel is the first known nonbiblical reference to the people by name. Whether the destruction was in the intervening desert or in Canaan (and whether a true or a false claim) is not clear. The tradition ascribes to Moses the basic features of Israel’s faith: a single God, called YHWH, who cannot be represented iconically, bound in a covenant relationship with his special people Israel, to whom he has promised possession of (not, as with their forefathers, mere residence in) the land of Canaan. There is some dispute among scholars as to when such features as the Mosaic Covenant actually emerged and as to which of the traditional 12 tribes of Israel entered Canaan at the end of the period of wandering in the desert.
The biblical account of the conquest of Canaan is again, from the point of view of historical scholarship, full of legendary elements that express and commemorate the elation and wonder of the Israelites at these events. The conquest of Canaan—according to tradition, a united national undertaking led by Moses’ successor, Joshua—was a rather drawn out and complicated matter. Archaeological evidence tends to refute some of the elements of the biblical account, confirm others, and leave some open. According to the tradition, after an initial unified assault that broke the main Canaanite resistance, the tribes engaged in individual mopping-up operations. Scholars believe that Hebrews who had remained resident in Canaan joined forces with the invading tribes, that the other Canaanite groups continued to exist, and that many of them later were assimilated by the Israelites.
