Their worm - This figure is taken from Isaiah 66:24. See the notes at that passage. In describing the great prosperity. of the kingdom of the Messiah, Isaiah says that the people of God "shall go forth, and look upon the carcasses of the men who have transgressed against God." Their enemies would be overcome. They would be slain. The people of God would triumph. The figure is taken from heaps of the dead slain in battle; and the prophet says that the number would be so great that their worm - the worm feeding on the dead - would not die, would live long - as long as there were carcasses to be devoured; and that the fire which was used to burn the bodies of the dead would continue long to burn, and would not be extinguished until they were consumed. The figure, therefore, denotes great misery, and certain and terrible destruction. In these verses it is applied to the state beyond the grave, and is intended to denote that the destruction of the wicked will be awful, widespread, and eternal.

It is not to be supposed that there will be any "real" worm in hell - perhaps no material fire; nor can it be told what was particularly intended by the undying worm. There is no authority for applying it, as is often done, to remorse of conscience, anymore than to any other of the pains and reflections of hell. It is a mere image of loathsome, dreadful, and "eternal" suffering. In what that suffering will consist it is probably beyond the power of any living mortal to imagine. The word their, in the phrase "their worm," is used merely to keep up the "image" or "figure." Dead bodies putrefying in that valley would be overrun with worms, while the "fire" would not be confined to them, but would spread to other objects kindled by combustibles through all the valley. It is "not" meant, therefore, that every particular sufferer has a special worm, or has particular sins that cause remorse of conscience. That is a truth, but it does not appear that it is intended to be taught here.

Where their worm dieth not, and the fire is not quenched. The passage referred to, is in Isaiah 66:24, and as there, the words are spoken of such, as transgressed against the Lord; so here, of such as offended any of Christ's little ones, or were offended by an hand, a foot, or eye, and retained them: by their worm is meant, their conscience; for as a worm that is continually gnawing upon the entrails of a man, gives him exquisite pain; so the consciences of sinners, will be continually flying in their faces, bringing their sins to remembrance, accusing them of them, upbraiding them with them, aggravating them, tormenting them for them, filling them with dreadful anguish and misery, with twinging remorses, and severe reflections, and which will never have an end. This will be always the case; conscience will be ever distressing, racking, and torturing them; it will never cease, nor cease doing this office, and so the Chaldee paraphrase of Isaiah 66:24 renders this phrase, , "their souls shall not die"; but shall ever continue in the dreadful torments and unspeakable horrors of a corroding conscience; and by "the fire" may be meant the fire of divine wrath let into their souls, which will never be extinguished; and so Jarchi interprets the phrase in Isaiah 66:24, "their fire", "in hell". It is a tradition of the Jews (l), that the light, fire, which God created on the second day, "there is no quenching it for ever"; as it is said, "for their worm shall not die, neither shall their fire be quenched", Isaiah 66:24, the passage which is here referred to; the reason they give is, because it is the fire of hell; the sense of which is sometimes given by the Jewish doctors thus (m); "their worm shall not die" from the body, "and the fire shall not be quenched" from the soul.

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

(m) Their worm who will be cast into that flame.

9:44 Where their worm - That gnaweth the soul, (pride, self will, desire, malice, envy, shame, sorrow, despair,) dieth not - No more than the soul itself: and the fire (either material, or infinitely worse!) that tormenteth the body, is not quenched for ever. Isa 66:24.

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.
