“It was the secrecy of the early kabalists, who were anxious to screen the real Mystery name of the “Eternal” from profanation, and later the prudence which the mediaeval alchemists and occultists were compelled to adopt to save their lives, that caused the inextricable confusion of divine names. This is what led the people to accept the Jehovah of the Bible as the name of the “One Living God”. Every Jewish elder, prophet, and other man of any importance knew the difference; but as the difference lay in the vocalization of the “name”, and its right pronunciation led to death, the common people were ignorant of it, for no initiate would risk his life by teaching it to them. Thus the Sinaitic deity came gradually to be regarded as identical with “Him whose name is known but to the wise.”
When Capellus translates: “Whosever shall pronounce the name of Jehovah, shall suffer death”, he makes two mistakes. The first is in adding the final letter h to the name if he wants this deity to be considered either male or androgynous, for the letter makes the name feminine, as it really should be, considering it is one of the names of Binah, the third emanation; his second error is in asserting that the word nokeb means only to pronounce distinctly. It means to pronounce correctly. Therefore, the biblical name Jehovah may be considered simply a substitute, which, as belonging to one of the “powers”, got to be viewed as that of the “Eternal”.
There is an evident mistake (one of the very many), in one of the texts in Leviticus, which has been corrected by Cahen, and which proves that the interdiction did not all concern the name of the exoteric Jehovah, whose numerous other names could also be pronounced without any penalty being incurred. In the vicious English version, the translation runs thus: “And he that blasphemeth the name of the Lord, shall surely be put to death”, Leviticus xxiv., 16. Cahen renders it far more correctly, thus: “And he that blasphemeth the name of the Eternal shall die”, etc. The “Eternal” being something higher than the exoteric and personal “Lord”.”
