Revelation 9:1-6

Then the fifth angel sounded [his trumpet], and I saw a star (angelic being) that had fallen from heaven to the earth; and the key of the bottomless pit (abyss) was given to him (the star-angel). [Rev 20:1] He opened the bottomless pit, and smoke like the smoke of a great furnace flowed out of the pit; and the sun and the atmosphere were darkened by the smoke from the pit. [Gen 19:28; Ex 19:18; Joel 2:10] Then out of the smoke came locusts upon the earth, and power [to hurt] was given to them, like the power which the earth’s scorpions have. [Ex 10:12-15] They were told not to hurt the grass of the earth, nor any green thing, nor any tree, but [to hurt] only the people who do not have the seal (mark of ownership, protection) of God on their foreheads. [Ezek 9:4] They were not permitted to kill anyone, but to torment and cause them extreme pain for five months; and their torment was like the torment from a scorpion when it stings a man. And in those days people will seek death and will not find it; and they will long to die [to escape the pain], but [will discover that] death evades them. [Job 3:21]
