King James
Jonah Chapter 1
Verse 17 Now the Lord had prepared a great fish to swallow up Jonah. And Jonah was in the belly of the fish three days and three nights.
Sounds pretty clear to me. I would assume that if he truly went to hell that the Bible would be clear that his body stayed in the fish while his soul went to hell.
Chapter 2
1. THEN JONAH prayed unto the Lord his God out of the fish's belly.
2. And said, I cried by reason of mine affliction unto the Lord, and he heard me; out of the belly of hell cried I, and though heardest my voice.
3 For thou hadst cast me into the deep, in the midst of the seas; and the floods compassed me about; all thy billows and thy waves passed over me.
4. Then I said, I am cast out of thy sight; yet I will look again toward thy holy temple.
5. The waters compassed me about, even to the soul; the depth closed me round about, the weeds were wrapped about my head.
6. I went down to the bottoms of the mountains; the earth with her bars was about me for ever: yet hast thou brough up my life from corruption, O Lord my God.
7. When my soul fainted within me I remembered the Lord: and my prayer came in unto thee, into thine holy temple.
8. They that observe lying vanities forsake their own mercy.
9. But I will sacrifice unto thee with the voice of thanksgiving; I will pay that that I have vowed. Salvation is of the Lord.
10. And the Lord spake unto the fish, and it vomited out jonah upon the dry land.
This can be used as symbolization, but you go too far in assuming that Jonah went to hell. Otherwise, he had to be ressurected and placed back into the fish so he could be up-chucked on the beach. You description is such a hard stretch that it makes no sense whatsoever.
I will not say that it is not a good symbol of hell. But the seaweed would obviously be gastro-intestinal debris in the fish's belly. The fish would dive and take Jonah to the roots of the mountains. Some of this description may be before he was actually swallowed by the fish. But, obviously God heard Jonah's call OUT OF THE FISH'S BELLY!
What is not clear about this? And why can we not take the simplest meaning of the translation without adding our own theories?
