The Name of God Y.eH.oW.aH Which is pronounced as it is Written I_Eh_oU_Ah

The understanding of God's name YHWH is so controversial that it is eventually the controversy of controversies or the ultimate controversy. Indeed why most of competent Hebrew scholars propagate patently false explanations about God's name? Why do the Jews refuse to read God's name as it is written and read Adonay my Lord (a plural of majesty) instead of it? Why God's name is usually punctuated eâ (shewa qamats) by the Masoretes what makes its reading impossible because the 4 consonants of the name YHWH must have at least 3 vowels (long or short) to be read like the words 'aDoNâY and 'eLoHîM God (a plural of majesty) which have 4 consonants and 3 vowels? At last why the obvious reading Yehowah according to theophoric names which all begin by Yehô- without exception is so despised and why the simple biblical meaning He will be from Exodus 3:14 is rejected.
