I found it astonishing how JWs analyze every minute detail of Greek and Hebrew (allegedly) to work out the days we live in and yet don't even know how their god's name is pronounced. It just seems weird to me.
Apparently calculating dates and chronology is much easier then getting names perfect because in Hebrew there were no vowels written. How names really sounded is just guesswork.
Like most early Semitic alphabetic writing systems, the alefbet has no vowels. People who are fluent in the language do not need vowels to read Hebrew, and most things written in Hebrew in Israel are written without vowels.
However, as Hebrew literacy declined, particularly after the Romans expelled the Jews from Israel, the rabbis recognized the need for aids to pronunciation, so they developed a system of dots and dashes called nikkud (points). These dots and dashes are written above, below or inside the letter, in ways that do not alter the spacing of the line. Text containing these markings is referred to as "pointed" text. Pronunciations are approximate.
My name: Ds-Mmbr could be pronounced a thousand different ways of you insert all the possible vowel variations.
We really don't have a clue what God's name is. What right does anyone have to just make one up for him?
