Even if that were true, there'd be no way to tangibly verify it. It would require faith in the expert claim, but it's bogus on its face because plenty are not divisible by 7.
Perhaps what you are referring to are studies on Gen 1:1. The verse is not divisible by 7 but there are some popular charts out there wrt Gen 1:1 and 7s.
There's a certain type of divine justice at work, when it turns out that people miss, reject, or mock the obvious because it's a dumb pun, even as they will embrace teachings that no one can prove. Some even get nasty when others won't believe "on faith" and/or the too-big-to-fail reasoning.
Case in point (which leads back to the thread topic):
Most English-language Bibles begin with, "In the beginning, Go-"
, which could be easily attacked from any number of directions because "that's not what it says.". Yet it's a basic statement of fact: the beginning *is* the place to start, so it's the simple meaning, located right out the gate.
But but but...
The beauty of word plays is that they exist even when no one intends them. Hence the common expression, "No pun intended."
A pun simply exists, even if the audience or the readers don't catch it, or even if the person saying it doesn't know.
The Bible is full of naming puns and yet for certain names, there are debates over what word play the namer had in mind.
Okay, all that means is that someone has not yet recognized the pun and/or the humor involved.
Here's a modern parallel:
Cousin Eddie named his "pride and joy" "Snots" because "he's got this sinus condition..."
He explained why he chose the name, but if a foreigner does not know the lingo, he might spend his time looking up names for sinus conditions in order to discover which one is named "Snots." Meanwhile, the "common people" laugh.
It's almost New Year's, a new beginning which is "from the ending of..", because it is a custom to keep an eye on the ball. :)
Heh, there's even the situation of Moses having a speech impediment.
There was not any prophet like Moses.
Looks like the problem was solved with the inevitable inflation, and ultimately by way of "forever" stamps.
