God isn't his name, it's a label identifying a supreme being of some sort. In the Judeo-Christian-Muslim world it all translates to simply "G/god" as a label. The God, Yahweh, Jehovah, and Allah are merely various translations of the same label. When Moses asked "God" what his name was, he said "I am who I am" which pretty much means it's none of your business to know. If I am not mistaken, early biblical writings simply left a blank anytime they wished to reference "God".
Since I'm bored with coed scouts...
I think the early biblical writings would be the Torah Actually, I got curious. In the dead sea scrolls the name of God is not blank, but it does use a different alphabet, or maybe it's just a different font.
Anyway, the YHWH, called the tetragrammaton, is from the hebrew יהוה or Yud Heh Vav Hey, which could be translated as "he" plus the root of the verb "to be" and likely comes from Exodus where Moses asks God for his name and God says something that can be translated a dozen different ways (He is who He is, I am what I am, I shall be what I am, He shall be who I am, I am who I am, .....).
Somewhere along the line the Catholic church wanted a Latin version of the tetragrammaton and translated YHVH into JeHoVaH. Maybe Latin doesn't have a Y?
But, back to not writing it or pronouncing God's name. Throughout the Bible God is referred to by either the tetragrammaton or one of many nicknames. The tetragrammaton is never pronounced and it's usually pronounced Adonai, which oddly enough translates to "my Lords". The idea behind not pronouncing God's name is not so far off. Kings get new names when they're anointed and using their original name is considered rude. Even using someone's first name, if you don't know them well, is, or was, also considered rude. There are native American tribes where people are given a secret name that only the person and the medicine man knows. Used in the right way this name was considered to have healing powers and used in the wrong way was bad. Anyway, God's name is never mentioned.
Even if anyone wanted to pronounce it they wouldn't know how because there are no vowels in the original text and unless someone told you what the vowels are, you couldn't say it. At one point in time there was someone that knew how to pronounce God's name and that was the high priest. It was passed down from high priests to high priest. The high priest only mentioned it once a year at the end of the high holidays after 10 days of prayer. And he had a special room in the temple where he said it and nobody else was allowed in that room. What I've been told, and I have no idea of it's validity because I find this rather humorous, is that there was another high priest that acted as a backup just in case the first team high priest got sick, died or whatever. That brings up the scenario of what if the high priest dies in the room? Apparently they tied a rope around him and if he didn't walk out they pulled him out and sent in the backup.
Well, after the destruction of the 2nd temple the priesthood ended and Rabbinic Judaism started, and one thing that was lost in the transition was the pronunciation of God's name. That's why Jews never pronounce God's name.
Back to the regularly scheduled subject....
