Where the Hebrew Scriptures got into "trouble" was with the introduction of gematria by mystical Rabbis and the deliberate effort on the part
of copyists to arrange the acrostic patterns to imply certain esoteric "meanings".
These acrostics only work if the text is not FURTHER COPIED in any but the identical form of the original.
Further, the loss of the KEY would disable efforts at uncorking the hidden texts.
In both Greek and Hebrew the letters did double-duty as numbers. A whole mystical catalog of supernatural importances was inferred by
employing letters as numbers and vice-verse.
Let's face it, these people didn't have cable TV, iPods, movies, internet or Disney world. For them, this was high entertainment.
