Shabbos and miqdash are the artificial superpositions of sanctity into time and place. They temper and create manageable rhythms and legions to defend territories respectively superimposed on the profane commercial and military sectors.
Shabbos addresses the function of money and installs a sacred interim where money transactions are suspended and the action of money cannot operate. Shabbos controls time, and in the commercial sector money is time.
Miqdash addresses the function of place and installs a consecrated space where location loses its sacred power.
The House of David unfortunately understood neither shabbos nor miqdash. It likely never instituted shnat sheviit, and it fixed the miqdash and thus merely intensified rather than suspended the sanctity of a particular place, to this very day.
