Even Einstein, Jewish, but not a JW, used the word "Jehovah" .
In a letter to a friend he asked "Where is the old jehovah, ca. 1015, when casualties. perhaps among his jewish friends mounted. quoted from the book "Einstein in Berlin"
Is there a text, where Jesus, the other great jewish expert on science (flat earther and supporter of the Noah's deluge, Jonah's 3 days holding his breath in stomach acid) ever addressed his father as the big "J"?? He probably would not dare call his carpenter stepfather "Hey, Joseph" either.
just treating the talking snake story as worthy of comment.
