Here's the best example I know of a bible story being real and having a religious interpretation which a reader can take or leave, i.e. of the whole thing being written in a subjective language which is so alien to us moderns as to cause most to simply jettison the story, mistakenly.
There is zero reason to expect an ancient author, Isaiah in this case, to make an obscure reference without bothering to explain the reference if it adds nothing to the story he's trying to tell. That would just be making work for himself unnecessarily.
In Isaiah 30:26, Isaiah speaks of the end of the world in future time, and notes
Quote:
...the light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold, as the light of seven days.
Most would assume he means cramming seven days worth of light into one day, but that is wrong. Midrashic sources including Louis Ginzberg's "Legends of the Jews" indicate that he is referring to the seven days which preceeded the flood and which are mentioned twice in the space of a paragraph around Genesis 7:4
Quote:
Gen. 7:4 "For yet seven days, and I will cause it to rain upon the earth forty days and forty nights;...
Gen. 7:10 "And it came to pass after seven days, that the waters of the flood were upon the earth."
The sentence should have been translated "The light of the sun shall be sevenfold, as the light of THE seven days."
Midrashic sources claim that God "turned on the primordial lights of the universe" for the week preceeding the flood in commemoration of the death of Methusaleh, who had died at the time.
What they're really saying is that there was a cosmic event of some sort in or close to our own system, followed by seven days of intense light and radiation, followed by the flood, which most scientists view as a fairytale.
Except that, when you strip the religious interpretation out of the story, you have a story which makes a lot of sense, and hangs together logically. The clear-cut implication is that the Noachean flood was part of some larger solar-system-wide calamity.
