Revelation 9:2-6

He opened the shaft of the bottomless pit, and from the shaft rose smoke like the smoke of a great furnace, and the sun and the air were darkened with the smoke from the shaft. Then from the smoke came locusts on the earth, and they were given power like the power of scorpions of the earth. They were told not to harm the grass of the earth or any green plant or any tree, but only those people who do not have the seal of God on their foreheads. They were allowed to torment them for five months, but not to kill them, and their torment was like the torment of a scorpion when it stings someone. And in those days people will seek death and will not find it. They will long to die, but death will flee from them.
