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. 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 the air were
darkened by reason of the smoke of the pit And there came
out of the smoke locusts upon the earth: and unto them was given power, as the scorpions of the earth have power. Revelation
9:1-3
And they had a king over them, which is
the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon.
Revelation 9:11
