These four letters that you see above is known as the Tetragrammaton, The Four Letters, YHVH or YHWH.
The Sacred Name Movement's objective is to discover the correct pronunciation of this image of Four Letters also called Tetragrammaton and the Great Name by Kabbalist and Jewish Mystics.
These four letters is where Christians get the GUESS names for God of Yahweh and Jehovah.
Today we can not know what the original vowels were.
Yahweh was actually twisted from the Aramaic (Babylonian Siriac alphabet) HAWA which is Aramaic for TO BE inserted under I Am That I Am from Exodus 3:14 and I AM definition from Strong's Concordance and Hebrew dictionary.
Finding that Yahweh is formed from the Aramaic HAWA TO BE.
Thus Yahweh is NOT FROM HEBREW but Aramaic, deemed to have been inserted by Babylonian Jewish scribes during their captivity adopting the Babylonian alphabet and language.
No, the name Jehova isn't a fabrication. If you're able to do that, just visit some of the old churches or cathedrals in Europe... some of them show passages calling God by his name Jehovah. One of those passages lasts from - if I'm not wrong - 1191, (
which is actually more than one thousand years AFTER the Hebrew bible was written, so it doesn't count as proof of anything)it actually is a fabrication, resulting from the first Christians learning Hebrew in the 12th Century, and misunderstanding a Jewish way of writing the vowels of the tetragrammaton in order to remind the reader to say the word for "lord" in place of the name.
Because the name was no longer pronounced and its own vowels were not written, its own pronunciation was forgotten. When Christians, unaware of the Jewish tradition, started to read the Hebrew Bible, they read יְהֹוָה as written with YHWH's consonants with Adonai's vowels, and thus said or transcribed
Iehovah. Today this transcription is generally recognized as mistaken, however many religious groups continue to use the form Jehovah, because it is familiar and because the correct pronunciation of יהוה is unknown.
YHVH is more than a name. It represents the totality of creation. The thorn of the Yod is Keter(will) which trandscends the creation. The letter yod itself is hokmah, which is gods wisdom, which in man is the seminal point of the intellect. The Heh is the container of the seminal point. Its the understanding that expands upon the seminal point of hokmah. Vav is the neck, it represents a contraction from intellect to emotion. This is shown by its shape, a line that descends. In the microcosm(man), the thinning of the neck signifies this contraction. And lastly the final heh is the level of action (עשיה - asiyah).
