And I said when I posted it that I hadn't seen it before.
And, I still don't know that it's true, just that it's an idea someone has that king Terru could be Terah. But even if it is true, why doesn't the story of Abraham mention that his dad was a king?

Regardless, quoting one of the most famous bits of the ten commandments to me (which obviously I've heard before) doesn't answer my question.
