{A great voice saying} (ph(936e)(886e) megal(886e) legousan).
Accusative after (886b)ousa in this phrase as in  5:11  10:4  14:2  18:4 , but the genitive ph(936e)(8873) legous(8873) in  11:12  14:13 . We
are not told whence this voice or song comes, possibly from one
of the twenty-four elders (Swete) or some other heavenly beings
( 11:15 ) who can sympathize with human beings ( 19:10 ), the
martyrs in heaven (Charles). {Now is come} (arti egeneto).
Arti ( Joh 13:33 ) shows how recent the downfall of Satan here
proleptically pictured as behind us in time (aorist tense
egeneto). {The salvation} (h(8820)s(9374)(8872)ia). Here "the victory" as
in  7:10  19:1 . {The power} (h(8820)dunamis). Gods power over the
dragon (cf.  7:12  11:17  19:1 ). {The kingdom} (h(8820)basileia).
"The empire of God" as in  11:15 . {The authority of his Christ}
(h(8820)exousia tou Christou autou). Which Christ received from the
Father ( Mt 28:18  Joh 17:2 ). See  11:15  ( Ps 2:2 ) for "his
Anointed." {The accuser} (ho kat(8867)(9372)). The regular form,
kat(8867)oros, occurs in  Joh 8:10  Ac 23:30,35  25:16,18  and in
many MSS. here in  Re 12:10 , but A reads kat(8867)(9372), which
Westcott and Hort accept. It was once considered a Greek
transliteration of a Hebrew word, but Deissmann (_Light_, etc.,
p. 93f.) quotes it from a vernacular magical papyrus of the
fourth century A.D. with no sign of Jewish or Christian
influence, just as diak(936e) appears as a vernacular form of
diakonos. Only here is the word applied to Satan in the N.T. In
late Judaism Satan is the accuser, and Michael the defender, of
the faithful. {Of our brethren} (	(936e) adelph(936e) h(886d)(936e)). The
saints still on earth battling with Satan and his devices. {Which
accuseth them} (ho kat(8867)or(936e) autous). Articular present active
participle of kat(8867)ore(935c), old verb, to accuse, usually with the
genitive of the person ( Joh 5:45 ), but here with the
accusative. This is the devil's constant occupation ( Job
1:6f. ). {Day and night} (h(886d)eras kai nuktos). Genitive of
time. "By day and by night."
