I seem to remember a part in the bible where it says that giants or titans etc in chains falling down in sheol/hell/gehanna/hades cause earthquakes, but for the life of me I can't find it. I may have read it in Enoch or something, but I'm going nuts looking for it. Anybody know the verse I'm looking for or am I mistaken?
I think you're confusing this with Norse mythology. However, the confusion is understandable. The reference to angels in chains is in Jude vs. 6 (KJV):
And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.
This verse probably refers back to Gen. 6:1 -4 (again using the King James Version):
And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them, that the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose. And the LORD said, "My spirit shall not always strive with man, for that he also is flesh; yet his days shall be a hundred and twenty years. There were
giants in the earth in those days, and also after that, when the sons of God came unto the daughters of men, and they bare children unto them, the same became mighty men which were of old, men of renown.
The "giants in the earth" of the KJV is more correctly rendered
Nephilim more modern translations, which relates to a Hebrew word meaning "to fell," implying either that the Nephilim were a fallen race or that the were "fellers" i.e. tyrants. Josephus says of the Nephilim that they were the same as those whome the Greeks called giants (Gr.
gigantes).
The Book of Enoch spun out a mythology that the angels who went down and had sex with mortal women also corrupted the human race, teaching men the arts of war, etc. These angels were called the watcher angels, because God had assigned them the job of watching over the human race. Instead they corrupted men and had sex with their daughters. For this act of rebellion they were imprisoned in chains under the earth, a motif likely borrowed from Greek mythology, where the titans were chained in Tartarus. Hence the allusion in Jude vs. 6 to angels who left their "own habitation" being "in chains under darkness," i.e. under the earth.
In Norse myth the giant Loki is chained under the earth for engineering the death of Baldur. Not only is he chained, but he lies under a serpent that constantly drips venom from its mouth. However, Loki's wife is there catching the venom in a cup. Every time the cup fills up and she has to dump the poison, some of the dripping venom falls on Loki's face, causing him to writhe in agony. This, according to the myth, is what causes earthquakes.
