{A strong angel} (heis aggelos ischuros). Here heis =
a, just an indefinite article, not "one" as a numeral. {Took up}
((8872)en). First aorist active indicative of air(935c). {As it were a
great millstone} (h(9373) mulinon megan). Late adjective, in
inscriptions, here only in N.T., made of millstone (mulos,  Mt
18:6  Re 18:22 ), while mulikos ( Lu 17:2 ) means belonging to
a mill. This is not a small millstone turned by women ( Mt
24:41 ), but one requiring an ass to turn it ( Mr 9:42 ), and so
"a great" one. {Cast} (ebalen). Second aorist active of
all(935c), to hurl. {With a mighty fall} (horm(886d)ati).
Instrumental case (manner) of horm(886d)a, a rush, old word from
horma(935c), to rush ( Mt 8:32 ), here only in N.T. {Shall be cast
down} (leth(8873)etai). Future (first) passive of all(935c), the
same verb (ebalen), effective punctiliar future. Like a boulder
hurled into the sea. {Shall be found no more at all} (ou m(880a)heureth(8869) eti). Double negative with first aorist passive
subjunctive of heurisk(935c). See  9:6  for ou m(885c) with the active
voice of heurisk(935c). Already the old Babylon was a desert waste
(Strabo, XVI. 1073).
