what is the "spirit of the world"?, page-90

So, you say that God said one thing to Moses one moment and the next changed his mind. That would not be very clever coming from an omnipotent being. You did admit that the change is not hard to find.

In any case, Watchtower literature admitted that the name Jehovah is a concoction.

Extract from Is God's name Yahweh or Jehovah? Highlights are mine

Shortly before the first century A.D., it became common for Jews to avoid saying the divine name for fear of misusing it and breaking the second commandment ("You shall not take the name of the Lord, your God, in vain," Dt 5:11). Whenever they read Scripture aloud and encountered the divine name, they substituted another Hebrew word, "Adonai" (which means "Lord" or "my Lord"), in its place.

About the 13th century the term "Jehovah" appeared when Christian scholars took the consonants of "Yahweh" and pronounced it with the vowels of "Adonai." This resulted in the sound "Yahowah," which has a Latinized spelling of "Jehovah." The first recorded use of this spelling was made by a Spanish Dominican monk, Raymundus Martini, in 1270.
Interestingly, this fact is admitted in much Jehovah's Witness literature, such as their Aid to Bible Understanding (p. 885). This is surprising because Jehovah's Witnesses loathe the Catholic Church and have done everything in their power to strip their church of traces of Catholicism. Despite this, their group's very name contains a Catholic "invention," the name "Jehovah."

Jehovah's Witnesses have painted themselves into such a tight and embarrassing corner over their name Jehovah's Witnesses that they have to indulge in double jointed gyrations to justify such a name - to do otherwise would entail too much of a loss of face.
