Wrenzberg's Prediction of the Kingship of Israel

The Adam story is a brief narrative snapshot of Israel's entire story. Both start off great, both are marked by disobedience and end in exile. In Genesis 17, God promises to Abraham that he and Sarah will have not only descendants, but specifically kings as their descendants. This can be understood as a prediction of the monarchy. The description of the borders of the land in Genesis 15 was really a description of a later geopolitical reality.
