Revelation 9:1, 3, 5-6

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 there came out of the smoke locusts upon the earth: and unto them was given power, as the scorpions of the earth have power.

And to them it was given that they should not kill them, but that they should be tormented five months: and their torment was as the torment of a scorpion, when he striketh a man. And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them.
