'Sulfur' in the Bible

"{Nothing} remains for him in his tent; sulfur is scattered upon his dwelling place.

He will rain coals on [the] wicked. Burning sulfur and scorching wind [will be] the portion of their cup.

For Topheth has been prepared from yesterday; indeed, it is made ready for the king. He makes its pile of wood deep and wide; he makes fire and wood {abundant}. The breath of Yahweh burns in it like a stream of sulfur.

And its streams shall be changed to pitch and its soil to sulfur, and its land shall become like burning pitch.

And I will execute justice with him with a plague and with blood and {torrents of rain}, and hailstones; fire and sulfur I will cause to fall on him and on his troops and on many peoples who [are] with him.
