It's stupid because use of a name is not a signature. If I write George W Bush here does that mean that George W Bush had anything to do with my post ? After all by Buz's standard George W. Bush has signed his name ot my post !
It's also stupid because the Bible - the original manuscripts - never use "Jehovah". "Jehovah" is just an attempt to transliterate the actual name into German - and not a good one. (And yes it IS important that German is the intended language because that 'J' would be a 'Y' if it was English).
It's even more stupid because the NT books don't even use the name. Yes, Buz knows this because he tried this sort of trick before. If you believe that a book has to use the name Yahweh to come from God then you'd better throw out the Gospels, Paul's Epistles and the rest of the NT. Is Buz going to do that ? Of course not.
