Brimstone

Brimstone (sulfur) is a yellow, flammable mineral found in deposits around the Dead Sea and volcanic regions. Its association with fire and divine judgment pervades the Old Testament: the destruction of Sodom and Gomorrah is described as a rain of fire and brimstone from the LORD out of heaven (Gen. 19:24), and subsequent prophetic literature consistently evokes this event as the paradigm of sudden, total divine judgment (Isa. 34:9; Ezek. 38:22; Amos 4:11). The sulfurous springs and ancient volcanic activity around the Dead Sea region provided a natural basis for the imagery.

In the New Testament, brimstone is exclusively eschatological: the lake of fire and brimstone in Revelation (Rev. 19:20; 20:10; 21:8) is the ultimate destination of the beast, the false prophet, the devil, and those whose names are not in the book of life. The pairing of fire and brimstone from Genesis to Revelation creates one of the most consistent images of divine wrath in the biblical canon. The torment of Revelation's lake of fire “going up forever and ever” (Rev. 14:11) draws on the Sodom precedent to describe the irreversible and permanent nature of final judgment.
