'Sulfur' in the Bible

This is how I saw the horses in my vision: The horsemen had breastplates that were fiery red, hyacinth blue, and sulfur yellow. The heads of the horses were like lions’ heads, and from their mouths came fire, smoke, and sulfur.

A third of the human race was killed by these three plagues—by the fire, the smoke, and the sulfur that came from their mouths.

he will also drink the wine of God’s wrath, which is mixed full strength in the cup of His anger. He will be tormented with fire and sulfur in the sight of the holy angels and in the sight of the Lamb,

But the beast was taken prisoner, and along with him the false prophet, who had performed the signs in his presence. He deceived those who accepted the mark of the beast and those who worshiped his image with these signs. Both of them were thrown alive into the lake of fire that burns with sulfur.

The Devil who deceived them was thrown into the lake of fire and sulfur where the beast and the false prophet are, and they will be tormented day and night forever and ever.

But the cowards, unbelievers, vile, murderers, sexually immoral, sorcerers, idolaters, and all liars—their share will be in the lake that burns with fire and sulfur, which is the second death.”
