David fulfils the long-hoped-for ambition of all Israel in taking Jerusalem, and establishes himself there with the ark of God, the central, sacramental thing in the religion of the chosen people. He is unaware that his own kingly office is to become a no less venerated centre in the dynasty he founds. For to be king of Jerusalem entailed far-reaching consequences. To be the anointed of Israel gave him an office that could be set in rivalry beside the priesthood of the house of Aaron; and to the general populace of Israel (especially the tribes that had no love for Levi and what they deemed its pretensions) he, not the successor of Aaron, was the spiritual head of the nation.
