'Brimstone' in the Bible

Then the Lord rained down brimstone (flaming sulfur) and fire on Sodom and on Gomorrah from the Lord out of heaven,

‘The whole land is brimstone and salt, a burning waste, unsown and unproductive, and no grass grows in it; it is like the overthrow of Sodom and Gomorrah, Admah and Zeboiim, which the Lord overthrew in His anger and wrath.’

Upon the wicked (godless) He will rain coals of fire;Fire and brimstone and a dreadful scorching wind will be the portion of their cup [of doom].

For Topheth [in Hinnom] has long been ready;Indeed, it has been prepared for the [Assyrian] king.He has made it deep and wide,A pit of fire with plenty of wood;The breath of the Lord, like a river of brimstone (blazing sulfur), kindles and fans it.

The streams [of Edom] will be turned into pitch,And its dust into brimstone,And its land will become burning pitch.

With pestilence and with bloodshed I will enter into judgment with Gog; and I will rain on him torrents of rain with [great] hailstones, fire and brimstone on his hordes and on the many nations that are with him.
