There was a lot written a few years back about hidden codes in the Bible. I have an old friend who has studied that sort of thing extensively. This is not new. There have been claims of codes and hidden meanings in the Bible since the first century. There were those who claimed to have special knowledge, that is how the term gnostic was derived from the Greek word for knowledge, gnosis.
Jesus, at some level, addresses this in John 5:39 – 40. He tells those who have the first five books of the Bible memorized that they are missing the point. The purpose of the Old Testament, which was written primarily in Hebrew, was to lead them to Christ. They were not doing that. They were coming up with rules to live by based on what they saw in the Bible. In a real sense they were gnostic.
The Bible was written in a language that has grammar and vocabulary. The Holy Spirit directed men to write what they did using this language, 2 Peter 1:20 – 21. In my experience, there is enough in the text to deal with without looking for some code or hidden meaning. Especially, if one has not simply studied the Bible as it is in the first place.
