Over a thousand manuscripts have been found having the vowel points "Yehovah", which has been affirmed by Jewish sources, by which the name of the Messiah is derived, "Yeshuah". This is sufficient compelling enough evidence to know that "Yehovah" is the correct pronunciation of the old covenant name of God. Although I am not a "Jehovah's Witness", they were indeed right all along in the true pronunciation of the old covenant name, except that the pronunciation of the "J" has changed over time in English, so the correct pronunciation of the name using the modern sounds of the letters is "Yehovah", not "Jehovah".
