My point johnamos is that the name/word Jehovah was not uttered by Jesus , the Apostles , or any of his disciples in the Greek Text that the Jehovah`s Witnesses based their Kingdom Interlinear Translation on the word for word Greek to English translation printed by the WTB&TS.
Additionally the first edition of the "Aid To Bible Understanding " book published by the WTB&TS admitted that Jehovah was not the most accurate pronunciation of Gods name however that was the most popular name in use at the time. ( By Christendom of course ) Especially the Roman Catholic Church who have that name engraved on centuries old Churches around the world .
So rather than go for the more accurate name for God in the Old Testament / Hebrew scriptures they chose the more populous name for God used by Christendom that they continually condemn as the anti-Christ .
