But He can choose to NOT BE all powerful for that time.
That's an illogical religious belief/conclusion based upon blind faith. If such a hypothetical entity 'chooses' not to be "all-powerful" then it precludes being all-powerful according to that 'choice'. The conclusion is that, if such a choice can be made, the one making it isn't "all-powerful" after all and not the hypothetical entity its believers bargained-away their ability to reason for.
The name Jehovah means he causes to become.
No. "Jivah - Sanskrit, 'sky god', (u=yava/java), same as Jihvah, a pagan 'g-d' preceding the judiac plagiarismm. Jove - Hebrew/YHVH (Yahweh):
The tetragrammaton YHVH would then be "e-ah-va-ah." With the Greek/Roman Jove we can see it would be pronounced as "J-ah-va-ah." And taking the "Jah" and converting the "J" to a "Y" we would then have "Yah" and finally "Yah-va-ah." If we convert the "v" into a "w" as is done between YHVH and YHWH the name would be "Yah-wa-ah" or "Yahwaah."
Jove is then none other than Yahwah or Yahweh."
The Aegyptian neteru "Xeper", which preceded judeo-xtianity by thousands of years, means "to become/to come into being", and was symbolized by the scarab beetle. It has nothing to do with the, (much later), attempt to assimulate a pagan mythology into a jw cult's beliefs.
That is all precisely correct and, falcon, since you're already aware that I speak German, "Jehovah," is the final German translation of that name before translation into English. In German it would be pronounced, "Yehofa." "Yahveh" is probably the closest to the actual pronounciation, but we can't be sure because Old Hebraic didn't use any vowels, you just had to know. New Hebraic added vowels, so they were already guessing. After that everything was translated to Aramaic, Greek, Latin, German and into English, in other cases directly from Latin to English. This helps to explain the numerous discrepancies between the "modern" versions of the bible and other ancient biblical tests, like some Coptic texts, or the Dead Sea scrolls, discovered in a cave in Qumran in 1949.
Anyway, "Jehovah" is a totally fictitious and made up name, it has no relation to historical reality or even biblical scripture. Look up YHVH, El, Elohim or Adonai. Of course I understand that this entire discussion will be far too complex for the microminiature intellect like hitch has proven to be. It just amazes me how these christians would wish to school us when they know so little about about the history of their own religion.
