I'm seriously going to get to the bottom of the name Jehovah after my current project.
EOM, you can do this, but it's been done MANY times on this site. It's been researched and researched and researched. It is quite conclusive that the pronunciation of the tetragrammeton (YHWH) was lost, and it certainly wasn't anything close to "Jehovah". Yahweh seems to be more correct, but even this is not an accurate pronunciation of the original.
By combining the vowel signs of 'Adho.nay and 'Elo.him' with the four consonants of the Tetragrammaton the pronunciations Yeho.wah' and Yehowih' were formed. The first of these provided the basis for the Latinized form "Jehova(h)." The first recorded use of this form dates from the thirteenth century C.E. Raymundus Martini, a Spanish monk of the Dominican Order, used it in his book Pugeo Fidei of the year 1270. Hebrew scholars generally favor "Yahweh" as the most likely pronunciation.
Bruce Metzger, who criticizes the KJV's misusage of Jehovah, gives additional information:(7)
The form "Jehovah" is of late medieval origin; it is a combination of the consonants of the Divine Name and the vowels attached to it by the Masoretes but belonging to an entirely different word ....The word "Jehovah" does not accurately represent any form of the Name ever used in Hebrew. The use of any proper name for the one and only God, as though there were other gods from whom the true God had to be distinguished, began to be discontinued in Judaism before the Christian era and is inappropriate for the universal faith of the Christian Church.
Finally, the Jewish Encyclopedia (click here) says this about the name: A mispronunciation (introduced by Christian theologians, but almost entirely disregarded by the Jews) of the Hebrew "Yhwh," the (ineffable) name of God (theTetragrammaton or "Shem ha-Meforash"). This pronunciation is grammatically impossible; it arose through pronouncing the vowels of the "?ere" (marginal reading of the Masorites:
= "Adonay") with the consonants of the "ketib" (text-reading:
= "Yhwh")—"Adonay" (the Lord) being substituted with one exception whereverYhwh occurs in the Biblical and liturgical books.
The pronunciation was lost in antiquity. It doesn't matter anyway. Contrary to what JWs say, Jesus did not make sure that everyone knew the name "Jehovah" and used it. He showed that we now have a different relationship with God and we now call Him "Father". The slaves, the Jews, called God by His name, but we are now adopted as sons of God and have the honor of calling Him "Abba" or "Father".
