Revelation 9:1-3

Then the fifth angel sounded, and I saw a star from heaven which had fallen to the earth; and the key of the bottomless pit was given to him. He opened the bottomless pit, and smoke went up out of the pit, like the smoke of a great furnace; and the sun and the air were darkened by the smoke of the pit. Then out of the smoke came locusts upon the earth, and power was given them, as the scorpions of the earth have power.
