Revelation 9:1, 3, 5-6

And the fifth angel sounded, and I saw a star from heaven fallen unto the earth: and there was given to him the key of the pit of the abyss.

And out of the smoke came forth locusts upon the earth; and power was given them, as the scorpions of the earth have power.

And it was given them 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 it striketh a man. And in those days men shall seek death, and shall in no wise find it; and they shall desire to die, and death fleeth from them.
