Revelation 9:5-12

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] The locusts resembled horses prepared and equipped for battle; and on their heads appeared to be [something like] golden crowns, and their faces resembled human faces. [Joel 2:4] They had hair like the hair of women, and their teeth were like the teeth of lions. [Joel 1:6] They had breastplates (scales) like breastplates made of iron; and the [whirring] noise of their wings was like the [thunderous] noise of countless horse-drawn chariots charging [at full speed] into battle. [Joel 2:5] They have tails like scorpions, and stingers; and in their tails is their power to hurt people for five months. [Joel 2:6] They have as king over them, the angel of the abyss (the bottomless pit); in Hebrew his name is Abaddon (destruction), and in Greek he is called Apollyon (destroyer-king). The first woe has passed; behold, two woes are still coming after these things.
