Revelation 9:2 in the King James Version
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.
Context
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.
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.
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.
