Revelation 9:1-6

The fifth angel blew his trumpet, and I saw a star that had fallen from heaven to earth. The key for the shaft to the abyss was given to him. He opened the shaft to the abyss, and smoke came up out of the shaft like smoke from a great furnace so that the sun and the air were darkened by the smoke from the shaft. Then locusts came out of the smoke on to the earth, and power was given to them like the power that scorpions have on 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 God’s seal on their foreheads. They were not permitted to kill them but were to torment them for five months; their torment is like the torment caused by a scorpion when it stings someone. In those days people will seek death and will not find it; they will long to die, but death will flee from them.
