If this is at all an accurate view of the founding of the religion of Jehovah, then we are faced with the phenomenon of a nation practically adopting a new religion. We do not ignore "revelation" when we feel compelled to seek for natural causes which might prepare the way for this event; and this we may attempt by an enquiry into the meaning of the name "Jehovah."
It should be noted at the outset that "Jehovah" is a personal name, like that of Zeus or Poseidon, conveying the idea of some aspect of deity. The meaning of the name is exceedingly obscure. The general name for deity common to all Semites, and therefore belonging to the undivided primitive stock, is "El," meaning either "the Mighty One" or, and more in accord with Semitic conceptions of God, "the Leader." The meaning of the name "Jehovah" is difficult to discover, because in the first place the exact pronunciation of the word has been lost, probably beyond recovery.
The word "Jehovah" is a hybrid compound, and as a matter of fact was never used as a name for God until the Reformation. We can be certain only that the consonants of the word were _JHVH_ (or _YHWH_, Hebrew pronunciation). This extraordinary state of things is accounted for by the fact that for centuries the Hebrew Scriptures were "unpointed" or unvocalised--that is, the consonants only were written and the necessary connecting vowels were taught orally, and only retained in the memory for use when the Scriptures were read aloud. When in the Ninth Century A.D. it was likely that the pronunciation of the sacred language would be entirely forgotten, a device for its preservation was made whereby the vowel pronunciation was indicated by means of "points" placed chiefly underneath the consonantal text; very much like the dots and dashes used for vowels in Pitman's system of shorthand. When, however, it came to the "pointing" of JHVH, it was found that the pronunciation of this word had been entirely lost. Reverence for the name of God had become so exaggerated that, in reading aloud from the Scriptures, wherever the sacred name occurred another word had always been substituted. This word was one of respect, but of less marked exaltation--_Adonai_, equal to our word "Lord." The only course open to the punctuators was that of inserting under the consonants JHVH, the vowels (with suitable euphonic modifications) of the word _Adonai_, with the result that we get the conflate "Jehovah," a word which has become invested with so much solemnity to our ears, but which was certainly not the right pronunciation, and which has never been used by the Jews. Scholars have endeavoured, at present without any universally accepted result, to recover the lost pronunciation by linguistic enquiries, with the desire to discover what the word originally meant, in the hope that it would throw some light on the origin of the religion founded by Moses. In Exod. iii. 13 ff. (R. V. margin) we have the traditional explanation of the word, an explanation which is not altogether satisfactory from a grammatical point of view; the great Hebraist Ewald goes so far as to pronounce it highly artificial. It has been objected that the man who wrote this account, about 750 B.C., surely understood his own language. Probably; but that is not to say that he understood the etymology of it, for etymology is a new science, and has upset many popular derivations in the case of our own language. If the explanation given in Exodus is correct, and we cannot with certainty put anything much better in its place, then the meaning of the word "Jehovah" would be "He that is," perhaps an equivalent in Hebrew form to the Western idea of "The Eternal." Only one of the numerous guesses as to the meaning of the original name need be quoted here: that the word comes from a verb, _hawah_, meaning either "to fall," or "to blow." Similar ideas would seem to account for either of these meanings. "He who blows," looks like the name for the Tempest God, while "that which falls" has been taken to indicate a fallen meteorite, which may have been preserved as a symbol of Jehovah. When we remember the thunderstorms at Sinai, and the common belief that thunder was a special theophany of Jehovah, these ideas are not to be hastily dismissed as altogether incredible. Nor should we be prevented from considering such an idea from the prejudice that it would make the origin of the religion of Israel a piece of Nature-worship and superstition. God has taken man where He has found him, and none can dare to define the limits of childish and crude conceptions within which the Spirit of God can begin His work in man's mind.
