Revelation 9:1, 3, 5

Then the fifth angel sounded: And I saw a star fallen from heaven to the earth. To him was given the key to the bottomless pit.

Then out of the smoke locusts came upon the earth. And to them was given power, as the scorpions of the earth have power.

And they were not given authority to kill them, but to torment them for five months. Their torment was like the torment of a scorpion when it strikes a man.
