Revelation 9:2
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.
Furnace. The imagery of a fiery furnace as a place of punishment comes from the Old Testament prophets (e.g., Eze. 22:20–22, Dan. 3:6, Mal. 4:1) and appears in other Jewish texts (e.g., Enoch 98, 4 Ezra 7:36).
