"Then the 5th angel sounded, and I saw a
star from heaven which had fallen to the
earth; and the key of the bottomless pit was
given to him.
He opened the bottomless pit, and smoke
went up out of the pit, like
the smoke of a great furnace;
and the sun and the air were
darkened by the smoke of the
pit.
Then out of the smoke came
locusts upon the earth,
and power was given them,
as the scorpions
of the earth have power.. . ."
Revelation 9:1-3
