The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be TORMENTED WITH FIRE AND BRIMSTONE in the presence of the holy angels, and in the presence of the Lamb: And THE SMOKE OF THEIR TORMENT ASCENDENTH UP FOR EVER AND EVER: and THEY HAVE NO REST DAY NOR NIGHT.
–Revelation 14:10-11 (KJV)–

The devil that deceived them was cast into the lake of fire and brimstone,
WHERE THE BEAST AND THE FALSE PROPHET ARE,
and shall be tormented day and night for ever and ever.
–Revelation 20:10 (KJV)–

Where THEIR WORM DIETH NOT,
and THE FIRE IS NOT QUENCHED.
–Mark 9:48 (KJV)–
