{With a shout} (en keleusmati). Note this so-called
instrumental use of en. Old word, here only in N.T., from
keleu(935c), to order, command (military command). Christ will come
as Conqueror. {With the voice of the archangel} (en ph(936e)(8869)
archaggelou). Further explanation of keleusmati (command). The
only archangel mentioned in N.T. is Michael in  Jude 1:9 . But
note absence of article with both ph(936e)(8869) and archaggelou. The
reference may be thus indefinite. {With the trump of God} (en
salpiggi theou). Trumpet. See same figure in  1Co 15:52 . {The
dead in Christ shall rise first} (hoi nekroi en Christ(9369)
anast(8873)ontai pr(9374)on). {First} here refers plainly to the fact
that, so far from the dead in Christ having no share in the
Parousia, they will rise before those still alive are changed.
