Numbers are wonderfully flexible things that can manipulated into nearly any end result that the manipulator wants to see.
However, I have read of some amazing inferences which the Jewish cabalists have drawn from the numbers of words, letters and etc. associated with the OT scripture, including some scientific predictions only proved true a half millennia later in the 20th century.
So I would approach the area with extreme caution, but not necessarily discard it outright without looking closer.
I found an excerpt from GL Schroeder's book Genesis and the Big Bang online. Note that I do no subscribe to cabalist mysticism, but it's intriguing nonetheless. Cabalism is but a small part of the argument that Schroeder makes too, so don't make the mistake of assuming he all about ancient Jewish mysticism.
the cabalists theorized that at the instant of creation, God, filling all eternity, contracted. Within that contraction, the universe expanded.
The cabalists believed that only four of the ten dimensions are physically measurable within today's world. The other six contracted into submicroscopic dimensions during the six days of Genesis.
There was more in the book, and specifically about the conclusion they drew from the numbers of letters, words, syllable and correlations between verses on this basis.
The relevant books from Schroeder are:
- Genesis and the Big Bang: The Discovery Of Harmony Between Modern Science And The Bible
- The Hidden Face of God: Science Reveals the Ultimate Truth
- The Science of God: The Convergence of Scientific and Biblical Wisdom
(A word of caution, I have read on critique of Schroeder's Genesis and the Big Bang, stating he is a theistic evolutionist; I didn't see that, but it's been quite a few years since I read G&BB, so it could be his bent. I am an old-earth creationist, and I still think he is interesting reading).
