It is a plain coincidence.
In fact there are also codes found in other books aside from the Bible.
Michael Drosnin, an American journalist and author, best known for his writings on the Bible code, claimed he found the name of Yitzhak Rabin embedded in the Bible text by a sequence of every 4,772 letters. With the Bible text arranged in lines of 4,772 letters each, he saw that Rabin’s name (read vertically) intersected with a line (Deuteronomy 4:42, running horizontally) that Drosnin translated as “assassin that will assassinate.”
Deuteronomy 4:42 actually speaks of a manslayer who has killed unintentionally. Thus, many have criticized Drosnin’s arbitrary approach, claiming that his unscientific methods could be used to find similar messages in any text. But Drosnin stood his ground, issuing this challenge:
“When my critics find a message about the assassination of a Prime Minister encrypted in [the novel] Moby Dick, I will believe them.”
What was the result?
Professor Brendan McKay, of the Department of Computer Science at the Australian National University, took up Drosnin’s challenge and made extensive computer searches through the English text of Moby Dick. Using the same method described by Drosnin, McKay claims to have found “predictions” of the assassinations of Indira Gandhi, Martin Luther King, Jr., John F. Kennedy, Abraham Lincoln, and others. According to McKay, he discovered that Moby Dick also “prophesied” the murder of Yitzhak Rabin.
We do not need hidden Bible code. The apostle Paul very clearly wrote that “all Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, that the man of God may be fully competent, completely equipped for every good work.” (2 Timothy 3:16, 17) The clear and straightforward message in the Bible is not too difficult to understand or apply, but many people choose to ignore it. (Deuteronomy 30:11-14) The prophecies that are openly presented in the Bible give a solid basis for believing its inspiration. Unlike a hidden code, Bible prophecies are not arbitrary, and they do not ‘spring from any private interpretation.’—2 Peter 1:19-21.
