In the spirit of Passover, and the fact that Christian holidays such as Easter "borrowed" many of the elements of their beliefs from others, in this post I will argue that the best explanation for the Exodus, via Ockham's razor, is that it did not occur as depicted in the Old Testament, but is instead a story which was cobbled together from the stories of different groups, and was used to elevate the status of the Jewish kings, and to serve their political, economic, and social interests.
I will be looking at the Exodus from a historical materialist perspective, and will use historical and archeological evidence to support my arguments--unlike the traditional idealistic Christian perspective, which views the bible as the "words of God," in the strict and literal sense. Instead, I will be looking at the "conditions of production" of the Exodus story that explains why it was written.
Considering the Israelites were at one point in time, nomads and slaves, it makes logical sense that their kings (namely Solomon and Josiah) employed hyperbole to create scenarios that elevated their status. In fact, some of the earliest known written works in the bible are from 1 Kings 1 and 2, and 2 Sam 9:20--the narration of the succession of David. Scribes of kings are known to exaggerate claims of the rulers who employ them, and this too can be said for the writers of the bible in their efforts to elevate their status in the world. This is how the story of the Exodus evolved.
