In a previous post I spoke about the reason why we Jews never pronounce the Holy Name as it’s wtitten in the Torah – יהוה
Rather, we use a different name אדני, Adonai, which means Master of All.
I’ve explained that uttering His Name explicitly, is a thing of the future to come, when indeed the meaning of that name is “uttered”, or externalized explicitly in the world, under the visible Government of HaShem. In other words, only when existence, the world itself, is complete and whole, and corrected, then will that name come forth unveiled.
Now the reason why it was explicitly pronounced in the Temple is, as I’ve explained, because the Temple is like a spark, a shred, of Olam Haba, the World to Come, imbeded in this nether world.
We are permitted, however, even in this imperfect world, even as our Temple is unfortunately destroyed, to meditate and muse upon the holy letters of the Explicit Name, when we utter the name ‘Adonay’.
All this is “hinted”, by way of Remez, in the numerical value (Gimmatria, or Gimtaryah) of the letters of this latter holy name, אדני.
Now, 65, is also the numerical value of the word היכל, Heychal, which means ‘hall’, or ‘shrine’.
It is also the Gimmatria of הס which means something like ‘be silent’ or even plain ‘shush’ or ‘hush’.
The Holy Name has to have a shrine in which to reside. So when we are inside the real shrine – the Temple when it’s built, then we can say His Name out loud. But when it’s not, then – hush! So if it’s written, say in a Torah scroll, we pronounce a name which is like a shrine to hold an conceal his glory, though it is there, in our minds and hearts, in our intention, כוונה.
And so says the verse in Habakkuk:
וַיהֹוָ֖ה בְּהֵיכַ֣ל קׇדְשׁ֑וֹ הַ֥ס מִפָּנָ֖יו כׇּל־הָאָֽרֶץ
And HaShem (the Holy Explicit Name, now pronounced Adonai) in his shrine of sanctity, all the Earth is hushed before Him.
Sums it all up, doesn’t it?
