Sorry for the segmented responses (one of those busy days)...
Difficult to relate to, but they definitely had an internal logic of their own.
There are so, so many - it's really quite fascinating and beautiful when you dig into it and really try to immerse your head in their way of thinking as evidenced to us archaeologically and anthropologically.
For instance; here's a simple flip that, if you consider the ramifications in conception, is rather far reaching.
The old Hebrew description and reference to time in direction is opposite to how we speak today.
Today, we think of time (not in physics, but in common conception day-to-day) like standing on a path with the past behind us and the future before us; standing upon the present.
However, in their way of conception you have to turn around and walk backwards in that metaphor to represent time; the past lays before you and the future lays behind you, and you stand upon the present.
There's a sort of charm to this, as well, for it makes tangible sense: you can see the past, so that is what you can face. You cannot see the future, so it is to your back (in the LDS thread, I cited a phrase regarding hiding from the face of another being an idiom of shame; here there is a shared cultural value - that of the face and witness or observation).
For even further reaching impacts, like many cultures of the region; the Hebrew concept of time wasn't linear...exactly.
Here's the best way I have figured out as a way to try to convey it:
Take a spiral staircase.
We'll just pretend it only has 4 steps before you have made a full circle starting on the 5th step.
Step 1 and 5 are the same degree position, but at different elevations.
Now, instead of upright like a stairwell, lay it horizontal like Archimedes' screw.
On step 1 and 5, put an event; like Sabbath, as an easy sample.
The idea of Sabbath, or any ritual holiday, (not so much now, but way back in these early times) was conceived like repeating an already done action, but with a new instance.
This is a bit hard to grasp how this works, but the only way I have found that best represents that ancient view of same action, different actors, is like pouring water from a pitcher into a cup, but in so doing, focus on each water molecule as unique and try not to lump it together as "water".
Now when you pour, because the boundaries of the physical objects involved, the water flows in a given range of motions.
When you pour a second time, you end up with relatively the same motions, but the molecules have changed to different molecules - same type of molecules, but different specific individual molecules.
So mix Archimedes' screw with the water metaphor and you start to get how "time" and "action" were conceived.
They were conceived almost like a giant machine - actions repeated by the same roles, but the actors playing those roles would change.
Not only was this often times seen as what just happened, but it became something which was purposefully sought to fulfill.
Why?
Well, mix these ideas with that previous bit about knowledge and god fearing and it starts to make a bit of sense from their viewpoint - this is the age where their civilizations were starting; where they were learning what it means to be a city, a state, a country, nation - many concepts they didn't even have names for, but were forging ahead with anyway.
There was a large amount of uncertainty and the stars clearly moved in a mechanized order, events appeared to have repetition in form within society, grabbing knowledge was a dangerous endeavor and required a right-set approach to avoid harm, and gods were the keepers of all which made this giant machine of existence "tick" along.
It's only a matter of time until someone, from this setting, fiercely is compelled to try to fulfill some role or event because they fear not doing so will off-balance the machine of existence (if you will) and destroy 'everything'.
Under these kinds of considerations, the prophecies are not so much prophecies in the way we think, but more akin to a physicist claiming the probability of an electron reaction under a given setting in the lab (at least; to their perspective), but it's like that and mixed with the idea of a casting call - it's being broadcast that someone not only will, but also
needs to, fill this role.
The prophecy is something derived from an extant account, applied forward in role.
It happened before, so therefore, it will happen again anew.
If something happened entirely new; then that cog in the gears just hadn't rotated into action yet, but will again in the future.
"Anew" is a rather big concept as well.
Everyone (at this point, at least) is probably familiar with the Mayan long count calendar resetting at the "end" to a "new" era.
Well; that whole prophecy section in the Hebrew legends where a new land is made and a new go at everything is begun with physical bodies and everything...that is Eden's repeat point on the clock; that's their long-count "new era".
