The right reading of Scripture neither bifurcates the Old from the New Testament nor the literal from the spiritual sense of Scripture. In fact, "when there is a question about the true and full sense of any Scripture (which is not manifold, but one), it must be searched and known by other places that speak more clearly." Are you an audacious or an arrogant interpreter of Scripture? 2 Samuel 5:6-10 is a fascinating test case for a seriously literal, full, single sense, Christocentric understanding of Scripture. 

I know "manifold" (multiple or many) senses of Scripture are becoming all the rage amongst a few Protestant scholars, some pastors, and their seminarian whippersnapper acolytes. But a seriously single sense of Scripture should be embraced by all Protestant believers because it emerges from Scripture itself. After all, the Reformation's "Dangerous Idea" is that the Bible was addressed to the populace at large and that because the Scripture is perspicuous and rational, a correct understanding is within everyone's reach. Scripture's message is sufficiently clear and evident to all who apply a due use of the ordinary means. 

The conquest of Zion as detailed in 2 Samuel 5:6-10 has deeper, not dual or quadruple, meaning. Let's take a look and scratch the surface on Jerusalem and Jesus: The Shadow of Christ in the Conquest of Zion.
