Where their worm dieth not, and the fire is not quenched. The Persic version renders it, "because from thence there can be no deliverance": which is rather an interpretation of these figurative expressions, and is a good one; since they design the eternity of hell torments, as well as point at the anguish and misery of them.

Where their worm dieth not, and the fire is not quenched.

9:41-50 It is repeatedly said of the wicked, Their worm dieth not, as well as, The fire is never quenched. Doubtless, remorse of conscience and keen self-reflection are this never-dying worm. Surely it is beyond compare better to undergo all possible pain, hardship, and self-denial here, and to be happy for ever hereafter, than to enjoy all kinds of worldly pleasure for a season, and to be miserable for ever. Like the sacrifices, we must be salted with salt; our corrupt affections must be subdued and mortified by the Holy Spirit. Those that have the salt of grace, must show they have a living principle of grace in their hearts, which works out corrupt dispositions in the soul that would offend God, or our own consciences.
