“We must now give some proofs of what we have stated, and demonstrate that the word Jehovah, if Masonry adheres to it, will ever remain as a substitute, never be identical with the lost mirific name. This is so well known to the kabalists that in their careful etymology of the 
, they show it beyond doubt to be only one of the many substitutes for the real name, and composed of the two-fold name of the first androgyne – Adam and Eve, Jod ( or Yodh), Vau and Heva – the female serpent as a symbol of Divine intelligence proceeding from the ONE-Generative or Creative Spirit.
Thus, Jehovah is not the sacred name at all. Had Moses given to Pharoah the true “name”, the latter would not have answered as he did, for the Egyptian King-Initiates knew it as well as Moses, who had learned it with them. The “name” was at that time the common property of the adepts of all the nations in the world, and Pharoah knew certainly the “name” of the Highest God mentioned in the Book of the Dead. But instead of that, Moses (if we accept the allegory of Exodus literally), gives Pharoah the name of Yeva, the expression or form of the Divine name used by all the Targums as passed by Moses. Hence Pharoah’s reply: “And who is that Yeva that I should obey his voice?”
“”Jehovah” dates only from the Masoretic innovation. When the Rabbis, for fear that they should lose the keys to their own doctrines, then written exclusively in consonants, began to insert their vowel-points in their manuscripts, they were utterly ignorant of the true pronunciation of the NAME. Hence, they gave it the sound of Adonah, and made it read Ja-ho-vah. Thus, the latter is simply a fancy, a perversion of the Holy Name. And how could they know it? Alone, out of all their nation the high priests had it in their possession, and respectively passed it to their successors, as the Hindu Brahmatma does before his death.
Once a year only, on the day of atonement, the high priest was allowed to pronounce it in a whisper. Passing behind the veil into the inner chamber of the sanctuary, the Holy of Holies, with trembling lips and downcast eyes he called upon the dreaded NAME. The bitter persecution of the kabalists, who received the precious syllables after deserving the favor by a whole life of sanctity, was due to a suspicion that they misused it. At the opening of this chapter, we have told the story of Simeon Ben-Iochai one of the victims to this priceless knowledge and see how little he deserved his cruel treatment.”
