Spike,
I know why the Aid was removed, as I am sure so do other here.
The "new" definition should have take into account what is on the WT website in the article "The Divine name that will endure forever", because it basically says the samething that the Aid book did.
Fact is, we have to be truthful in the admission that not only is the pronunciation of YHWH unknow, so is the spelling and until we have verifibale proof and not specualtion and possibilites, we can't say trutfully that, by say Jehovah, we are saying God's TRUE AND DIVINE name, because base don what we knwo eight now, that is NOT the case.
