{As for these things} (	auta). Accusative of general
reference. {One stone upon another} (lithos epi lith(9369)). Stone
upon stone (locative). Here both  Mr 13:2  Mt 24:2  have epi
lithon (accusative). Instead of ouk apheth(8873)etai (future
passive) they both have ou m(8820)apheth(8869) (double negative with
aorist passive subjunctive). It was a shock to the disciples to
hear this after the triumphal entry.
