The vowel pointings in the Aleppo and the St Petersburg codices show beyond a shadow of doubt that the name is Yehova.
There is no “w” sound in Hebrew names.
What other authority can there even be?
.
Just en passant, The way you teach people to make a ‘w’ sound is to have them make an ‘oo’ sound. If the vav stands for an ‘oo’ you have at lease the beginning of a ‘w’.
There’s an alternate exppanation for the vowel pointing.
If you write the Tetragrammaton and point it for adonai but with the changes the suit the Tetragrammaton, then you get Ye Ho Va pointing.
Im not a4guing either way. I’m reporting.
Also there is at least one source in Greek reporting an “iaoue” sort of thing. FWIW.
