The warning to beware of duplicitous scribes is soon followed by Jesus’ disciples pointing out the “wonderful stones” and “wonderful buildings” of the temple (13:1). It is to this which Jesus replies, “Not one stone will be left upon another” (13:2). This is ironic and disappointing. The disciples didn’t get it; they had missed the point. They have not been listening—a dangerous place to be, for this is the OT charge against Israel’s unprepared leadership. Yet all readers/listeners are to guard against their own unpreparedness at the (re)appearance of the Master of the house.
 Mark uses krima here, which means judgment and is most likely drawn from the Malachi reference (Mal 3:5).
 The drawing in of the readers/listeners can also be seen in the “hardening” texts directed at the disciples (Mark 6:51–52; 8:14–21).
