Remember Witnesses pointing out ALL that time that "By Jove" meant "By Jehovah."
Just to set the record straight: it's not "By Jehovah" it's "By Jupitor." You see in Latin, Jupitor is spelled thus: Iuppitor. But that's only in the nominative, for all the other cases it's Iovis, Iovi, Iovem, Iove. The last one is ablative and it is used in English because of the "by" word of the phrase "By Jove"; it's an ablative of agent. Now when they translated this into English, they just chaged the Latin I into the English J (actually, this is due to orthographical problems that originated, I believe, in the middle ages).
There you have it. Whenever you hear a JW using the argument "By Jove" to show the widespread use of Jehovah in the English language and it's subsequent destruction by the Churches you can say: "You're full of sh*t".
My rant for today is finished, you're lucky it's semi-coherent.
