Let us say that each Old and New Testament story has its own site, whether the whole 'dig' area or a part of it, whichever pleases you, the reader. Each separate story and each player has left his mark: his own portion of treasures to be unearthed, both independent and as they intertwine with others. The research as to the relevance of each is limited only by the desire of the seeker and the pleasure of the Holy Spirit at any given time.
