The vowels of the Name itself are hidden... it's vowels are the secret of the Tetragrammaton.
Elijah of Vilna, 18th Century
The Modern Encyclopedia is incorrectly interpreting the source (by stating the Jews don't know the vowels or name of Elohim).
Consonants YHVH - Vowels: Sheva, Cholam, Kamatz. ?
Exodus 3:14 is Ehyeh "I am". Ehyeh literally means "I will be". Yehovah is a combination of three forms of the same verb, "to be": haya ("He was"), hoveh, ("He is"), and Yihiyeh, ("He will be"). When you combine haya, hoveh, and yihiyeh (He was, He is, He will be) you get Yehovah. ? Le'olam לְעוֹלָם sheva, cholam, kamatz are the same vowels of YeHoVaH. ?
? And Elohim said further to Mosheh, “Thus you are to say to the children of Yisra’ĕl, ‘יְהוָֹה Elohim of your fathers, the Elohim of Aḇraham, the Elohim of Yitsḥaq, and the Elohim of Ya‛aqoḇ, has sent me to you. This is My Name forever, (לְעוֹלָם Le'olam) and this is My remembrance to all generations.’
Shemoth (Exodus) 3:15 TS2009
Shem ha-Meforash the Hebrew phrase for the Tetragrammaton יהוה YHVH (yod, hei, vav, hei) for the name יְהֹוָה YeHoVaH.
Le'olam (לְעוֹלָם) is Shach"ak the acronym for the vowels (sheva, cholam, kamatz) of יְהֹוָה.

In Exo 3:12 אהיה = Ehyeh - "I will be" with you.
In Exo 3:14 Ehyeh Asher Ehyeh - I will be what I will be.

The Hebrew word for love is ahavah. In Psalm 91:14 it's a completely different word for love, it's cha-shak (Shach"ak). An acronym that represents the pronunciation of the Name --
Sheva, cholam, kamatz, those are the three vowels to the name יְהֹוָה Yehovah.

It's mnemonic is "Who in heaven (shach"ak) can measure up to you..." (Ps 89:6[7])
Shach"ak is an acronym for the vowels [sheva cholam, kamatz].

?Psalm 91:14
“Because he cleaves to Me in love, Therefore I deliver him; I set him on high, Because he has known My Name.
Tehillim (Psalms) 91:14 TS2009

In the Jewish mindset, there has always been a dualistic view of history: this age, Olam Hazeh, and future age, Olam Haba with the future reign of HaMashiach, the age to come, when יְהֹוָה would vindicate His people.
This is a message of Hope, one day Yisra’ĕl will have ??shalom. ?
?The ban on the name is only for now.
This world is not like the world to come (the Kingdom under the reign of HaMashiach on earth). This world the exile is not like the Kingdom of HaMashiach. In this world the Name is written YHVH and is read as Adonai. But in the world to come it will be one, written YHVH and read YHVH (Zechariah 14:9).
And behold when is read as YHVH in the world to come, then it's vowels will be Shach"ak.
Grammarian Rabbi Shabbethai Sofer 1608
??YeHoVaH יְהֹוָה??
