The Lake of Fire: Worms

And if your eye causes you to sin, pluck it out. It is better for you to enter the kingdom of God with one eye than to have two eyes and be thrown into hell, where "'their worm does not die, and the fire is not quenched.' Everyone will be salted with fire.
Mark 9:47-49

I am I the only person who has wondered why Mark 9:48 mentions worms not dying? I did some research to see if I could uncover the meaning behind worms not dying.

Immediately, because Herod did not give praise to God, an angel of the Lord struck him down, and he was eaten by worms and died.
Acts 12:23

Here's something from "Antiquities of the Jews Book 17" (Chapter 6, verse 5) The following was NOT taken from the bible.

But the disease of Herod grew more severe, God inflicting punishment for his crimes. For a slow fire burned in him which was not so apparent to those who touched him, but augmented his internal distress; for he had a terrible desire for food which it was not possible to resist. He was affected also with ulceration of the intestines, and with especially severe pains in the colon, while a watery and transparent humor settled about his feet. 
He suffered also from a similar trouble in his abdomen. Nay more, his privy member was putrefied and produced worms. He found also excessive difficulty in breathing, and it was particularly disagreeable because of the offensiveness of the odor and the rapidity of respiration. He had convulsions also in every limb, which gave him uncontrollable strength. It was said, indeed, by those who possessed the power of divination and wisdom to explain such events, that God had inflicted this punishment upon the King on account of his great impiety

I don't know how reliable this source is, but it seems to match up with scripture, Herod was eaten by worms. Yes, it's nasty, but I think "their worm does not die" from Mark 9:48 is speaking of King Herod disease. Hell a pleasant subject, but it's an important one.

Do not be afraid of those who kill the body but cannot kill the soul. Rather, be afraid of the One who can destroy both soul and body in hell.

Mathew 10:28

In their greed these teachers will exploit you with stories they have made up. Their condemnation has long been hanging over them, and their destruction has not been sleeping. For if God did not spare angels when they sinned, but sent them to hell, putting them into gloomy dungeons to be held for judgment; if he did not spare the ancient world when he brought the flood on its ungodly people, but protected Noah, a preacher of righteousness, and seven others; if he condemned the cities of Sodom and Gomorrah by burning them to ashes, and made them an example of what is going to happen to the ungodly; and if he rescued Lot, a righteous man, who was distressed by the filthy lives of lawless men (for that righteous man, living among them day after day, was tormented in his righteous soul by the lawless deeds he saw and heard)--if this is so, then the Lord knows how to rescue godly men from trials and to hold the unrighteous for the day of judgment, while continuing their punishment.

2 Peter 2:3-9

The sea gave up the dead that were in it, and death and Hades gave up the dead that were in them, and each person was judged according to what he had done. Then death and Hades were thrown into the lake of fire. The lake of fire is the second death. If anyone's name was not found written in the book of life, he was thrown into the lake of fire.

Revelation 20:13-15
