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.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.

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—On the words "hell" and "hell-fire," or "the hell of fire," see on [1467]Mt 5:22. See Poole on "Mark 9:43"

And if thine eye offend thee, pluck it out,.... Than which, nothing is dearer to man, it being very tender, and exceeding useful: this metaphor the Lord sometimes makes use of, to show how dear his people are unto him, and what a tender concern he has for them, Deuteronomy 32:10. And here it may design such, as are most beloved by men, and are their most intimate acquaintance, and bosom friends; and yet these are to be parted with, when they prove snares and stumbling blocks, or give offence, by endeavouring to draw into sin, and from Christ:

it is better for thee to enter into the kingdom of God with one eye; that kingdom, which God has prepared for his people, from the foundation of the world, and of his rich grace, gives unto them, and in which they will enjoy him to all eternity;

than having two eyes, to be cast into hell fire. In the two instances before it is added, "that never shall be quenched".

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:
