Believers in the “Bible code” theory treat the Hebrew Bible as a string of letters without spaces, looking for words formed by equidistant letter sequences. For instance, computers might select every ninth Hebrew letter and register a “hit” when a “coded word” intersects with a Bible verse containing related words.

Major Bible scholars ignore the code because, they note, no one has a letter-by-letter version of the Bible as originally written. The oldest surviving manuscripts include slight variations, any of which would throw off computer test results.
