Introduction
THE FIFTH TRUMPET: THE FALLEN STAR OPENS THE ABYSS WHENCE ISSUE LOCUSTS. THE SIXTH TRUMPET. FOUR ANGELS AT THE EUPHRATES LOOSED. (Rev. 9:1-21)
The last three trumpets of the seven are called, from Rev 8:13, the woe-trumpets.
fall--rather as Greek, "fallen." When John saw it, it was not in the act of falling, but had fallen already. This is a connecting link of this fifth trumpet with Rev 12:8-9, Rev 12:12, "Woe to the inhabiters of the earth, for the devil is come down," &c. Compare Isa 14:12, "How art thou fallen from heaven, Lucifer, son of the morning!"
the bottomless pit--Greek, "the pit of the abyss"; the orifice of the hell where Satan and his demons dwell.
