For those not familiar with the Shashu people, and the original Yahweh or Jehovah , from Wikik :
" Regarding the name yhw3, Michael Astour observed that the "hieroglyphic rendering corresponds very precisely to the Hebrew tetragrammaton YHWH, or Yahweh, and antedates the hitherto oldest occurrence of that divine name – on the Moabite Stone – by over five hundred years."[7] K. Van Der Toorn concludes: "By the 14th century BC, before the cult of Yahweh had reached Israel, groups of Edomites and Midianites worshipped Yahweh as their god."
Notice the phrase " before the cult of Yahweh had reached Israel " . Our Hebrew/Jewish friends were a little late to the Party, and similar to many peoples, borrowed their god from neighbouring peoples.
This will come as a shock to most JW's.
