Why were these books put together? The first thing to realize is that the very motive behind their composition around Deuteronomy at this time was the nostalgic anguish for the lost bicamerality of a subjectively conscious people. This is what religion is. And it was done just as the voice of Yahweh in particular was not being heard with any great clarity or frequency. Whatever their sources, the stories themselves, as they have been arranged, reflect human psychologies from the ninth century up to the fifth century B.C., the period during which there is progressively less and less bicamerality.
