Another thought on the matter. When you say that the text has to mean something .... you are aware, yes?, that you have presented to us three verses from which to extract meaning.
And yet those 3 sentences are part of a much longer story cycle.
Many, many people have presented a set of paragraphs, or even the whole chapter. And so, in the process, many sentences are set aside because they are not seen as "central" to the allegory or parable in question.
By limiting your selection to 3 sentences, you pretty much intend to limit the room for interpretation!
So this makes another aspect of your proposed challenge relatively invidious.
•(of a comparison or distinction) unfairly discriminating; unjust.
synonyms: unpleasant, awkward, difficult; More undesirable, unenviable.
Let's list the relevant factors, compared to the Job text on Snow/Hail
A. 3rd Person statement in Genesis, vs. a Quote from Yahweh in Job
B. A 3 sentence fragment of a much bigger story cycle,
vs. a 2 part comparison within a long chain of 2 part comparisons.
C. The text in Genesis says God is done creating, but doesn't say there will be no further creations, and doesn't actually specify animals. After the 6th day, there is an assertion that no more animals can be created, but this would leave the following conundrums: i) Hyper-creation after the animals leave the ark? ii) Hyper-creation found in the Australian marsupials who spread-out to fill ecological niches filled by placental mammals elsewhere in the world; iii) the animals that don't appear to have been around before the flood, but suddenly appear after the flood?
The text in Job is of a known fictional device (treasury or warehouse) combined with a fictional practice (storing snow & hail for use on Earth at the right time).
