"Where their worm dieth not, and the fire is not quenched." (Mark 9.48; also in verse 44 and 46, the same words).
Isa 66:24 And they shall go forth, and look upon the carcases of the men that have transgressed against me: for their worm shall not die, neither shall their fire be quenched; and they shall be an abhorring unto all flesh.
