Many examples have been documented in the past. One cited example is that by taking every 50th letter of the Book of Genesis starting with the first taw, the Hebrew word “torah” is spelled out. The same happens in the Book of Exodus. Modern computers have been used to search for similar patterns and more complex variants, as well as quantifying its statistical likelihood.
Some tests purportedly showing statistically significant codes in the Bible were published as a “challenging puzzle” in a peer-reviewed academic journal in 1994.
