Revelation 9.1 The fifth angel sounded, and I saw a star from the sky which had fallen to the earth. The key to the pit of the abyss was given to him. 9.2 He opened the pit of the abyss, and smoke went up out of the pit, like the smoke from a burning furnace. The sun and the air were darkened because of the smoke from the pit. 9.3 Then out of the smoke came locusts on the earth, and power was given to them, as the scorpions of the earth have power. -WEB Bible.
