Usually I am more interested in learning about real science than in debunking junk science. However the subject of Bible codes came up on another board that I subscribe to, and I just had to respond. Here is some background info from the Wikipedia article on the subject:

"Bible codes, also known as Torah codes, are words, phrases and clusters of words and phrases that some people believe are meaningful and exist intentionally in coded form in the text of the Bible. These codes were made famous by the book The Bible Code, which suggests that these codes offer warnings for the future.

The primary method by which purportedly meaningful messages have been extracted is the Equidistant Letter Sequence (ELS). To obtain an ELS from a text, choose a starting point (in principle, any letter) and a skip number, also freely and possibly negative. Then, beginning at the starting point, select letters from the text at equal spacing as given by the skip number.)"

Here is the link for the entire Wikipedia article:

There is nothing new here. ELS is similar to a cryptographic approach called Chaffing and Winnowing. With either technique, the sender of the message throws a lot of garbage in with the real information, to confuse would-be eavesdroppers. The intended receiver of the information has an algorithm for throwing out the garbage. With a reasonably high garbage/info ratio, casual eavesdroppers would have no way of knowing which of the many possible 'coded messages' was the real one.

I don't see how the putative Bible codes could deepen anyone's understanding of their religion, or of our day-to-day world. My educated guess is that there is a lot of wishful thinking and selective perception going on here. If your 'decoding' algorithm generates a 'hidden message' from Genesis that comfortably meshes with your belief system, you can say: Aha! On the other hand, if the algorithm generates an understandable message that you don't like, then you quietly put it into File 13, and conveniently forget about it.

In IT parlance, we can summarize Bible 'decoding' schemes as follows: Garbage in, garbage out.
