Revelation 9:1-3

Then the fifth angel sounded his trumpet, and I saw a star that fell from heaven to earth, and he was handed the key to the shaft leading down to the pit of the deep. He opened the shaft of the bottomless pit and a blanket of smoke began to rise out of it, like the smoke of a giant furnace. The sun and the atmosphere were darkened with the smoke rising from the shaft. And out of the smoke appeared locusts swarming onto the earth, and they were given authority like that of scorpions to inflict pain.
