Revelation 9 (KJV)

1 And the fifth angel sounded and i saw a star fall from heaven onto the Earth: and to him was given the key to the bottomless pit
2 And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the Sun and air were darkened by reason of the smoke of the pit.
