Brimstone

Brimstone, or sulphur, is found in considerable quantities on the shores of the Dead Sea. (Genesis 19:24) It is a well-known simple mineral substance, crystalline, easily melted, very inflammable, and when burning emits a peculiar suffocating odor. It is found in great abundance near volcanoes. The soil around Sodom and Gomorrah abounded in sulphur and bitumen.

An inflammable mineral substance found in quantities on the shores of the Dead Sea. The cities of the plain were destroyed by a rain of fire and brimstone (Gen. 19:24, 25). In Isa. 34:9 allusion is made to the destruction of these cities. This word figuratively denotes destruction or punishment (Job 18:15; Isa. 30:33; 34:9; Ps. 11:6; Ezek. 38:22). It is used to express the idea of excruciating torment in Rev. 14:10; 19:20; 20:10.
