Mark 9:48 in the World English Bible
‘where their worm doesn’t die, and the fire is not quenched.’
Context
47 And if thine eye offend thee, pluck it out: it is better for thee to enter into the kingdom of God with one eye, than having two eyes to be cast into hell fire:
48 Where their worm dieth not, and the fire is not quenched.
49 For every one shall be salted with fire, and every sacrifice shall be salted with salt.
