* shall fall.
   This is an allusion to the Jewish mode of stoning.  "The place
   of stoning was twice as high as a man.  From the top of this
   one of the witnesses struck the culprit on the loins, and
   felled him to the ground:  if he died of this, well; if not,
   the other witness threw a stone upon his heart," etc.  Our
   Lord seems to refer not only to the dreadful crushing of the
   Jews by the Romans, but also to their general dispersion to
   the present day.
