{Be girded about} (est(9373)an periez(9373)menai). Periphrastic
perfect passive imperative third plural of the verb periz(936e)numi
or periz(936e)nu(935c) (later form), an old verb, to gird around, to
fasten the garments with a girdle. The long garments of the
orientals made speed difficult. It was important to use the
girdle before starting. Cf.  17:8  Ac 12:8 . {Burning}
(kaiomenoi). Periphrastic present middle imperative, already
burning and continuously burning. The same point of the Parable
of the Ten Virgins ( Mt 25:1-13 ) is found here in condensed
form. This verse introduces the parable of the waiting servants
( Lu 12:35-40 ).
