Revelation 9:3-6

Then out of the smoke came locusts upon the earth, and power was given them, as the scorpions of the earth have power. They were told not to hurt the grass of the earth, nor any green thing, nor any tree, but only the men who do not have the seal of God on their foreheads. And they were not permitted to kill anyone, but to torment for five months; and their torment was like the torment of a scorpion when it stings a man. And in those days men will seek death and will not find it; they will long to die, and death flees from them.
