And lets not forget
A roman Catholic Spanish Monk Justus Martinus of the 13th century first coined the name Jehovah using the 4 hebrew letters of the tetragrammaton then translated as JHVH and adding some vowels.to come up with Jehovah.
So in fact the Roman Catholic Church invented the name of God as Jehovah.and jehovahs Witnesses adopted that name instead of the more correct pronunciation of Yahweh. Hebrew never had a "J" sounding letter.
That is why some translations of the Bible use the letter y instead of j in their translations.E.G. Yosiah ,Yesus .etc.
