And the fifth angel blew his trumpet, and I saw a star that had fallen from heaven to earth, and he was given the key to the shaft of the bottomless pit;
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 authority like the authority of scorpions of the earth.
They were told not to damage the grass of the earth or any green growth or any tree, but only those people who do not have the seal of God on their foreheads.
They were allowed to torture them for five months, but not to kill them, and their torture was like the torture of a scorpion when it stings someone.
And in those days people will seek death but will not find it; they will long to die, but death will flee from them.
In appearance the locusts were like horses equipped for battle. On their heads were what looked like crowns of gold; their faces were like human faces,
their hair like women's hair, and their teeth like lions' teeth;
they had scales like iron breastplates, and the noise of their wings was like the noise of many chariots with horses rushing into battle.
They have tails like scorpions, with stingers, and in their tails is their power to harm people for five months.
They have as king over them the angel of the bottomless pit; his name in Hebrew is Abaddon, and in Greek he is called Apollyon.
