Most of us have become so immersed in religion that we simply cannot understand G-d's direct revelation to us.  We have the tendency to hold onto what man has taught us instead of seeing the truth of Scripture.  If you are student of literature, you may study the Scriptures from the point of view of what man can do.  It thus becomes man's book instead of the Book of what G-d does.  Much of our halachah began with superstition and not actually what the Torah said.  We need to be careful not to put men's writings about G-d's.  In Vaera וארא  we see the precedence established concerning the use of the “name of G-d”—Ani Adonai, Ani haShem- אני יהוה

Rabbi Benno Jacob in his excellent commentary on the book of Exodus brings us an interesting perspective about the Tetragrammaton, יהוה the Name of G-d.  He was able to clarify the ideas which had developed in his day where the usage of Name of G-d had been given power and could then be used like an icon.  This had developed during the Greek period two centuries before the Common Era, BCE when they were influenced by Artaparrus, the Egyptian Greek Jew whose writings brought to us the idea of the other religions where by pronouncing the ineffable Name of G-d, some type of power was placed in our hands.  He brought the idea of comparing the god of Egypt with the G-d of Israel, making the mistake that the G-d of Israel was better than “Rah” the god of Egypt.  They had the idea that if they pronounced the name of their god it would be like hocus-pocus endowing them with the power to do anything.  After this idea was introduced into the Jewish writings, it motivated the rabbis to make the decision that we should avoid pronouncing the name of G-d due to its possible misuse thus protecting the sanctity of G-d’s Name.  They believed that  יהוה was so holy, powerful and pure that it couldn't be pronounced and thus was removed from the mouth of humanity.  Instead of making His Name known as He told Moses, we kept it a secret.  Here is only one of the many ways that man has changed the word of G-d.
