And the fifth angel sounded, and I saw a star fall from heaven unto the earth: and to him was given the key of the bottomless pit.
The last three trumpets of the seven are called, from Revelation 8:13, the woe-trumpets.
Fall - `fallen.' When John saw it, it was not falling, but had fallen already. This is a link joining this fifth trumpet with Revelation 12:8-9; Revelation 12:12, 'Woe to the inhabiters of the earth ... for the devil is come down,' etc. Compare Isaiah 14:12.
The bottomless pit - `the pit of the abyss:' the mouth of the hell to which Satan and his demons are doomed.
