Revelation 9:2 in the World English Bible
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.
Context
1 And the fifth angel sounded, and I saw a star fall from heaven unto the earth: and to him was given the key of the bottomless pit.
2 And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.
3 And there came out of the smoke locusts upon the earth: and unto them was given power, as the scorpions of the earth have power.
