I agree with that comment, but I also think that Norman DeWitt had read more Greek in his lifetime up to writing that book than any ten of us,
Fully agree without question, but...
I've voiced my misgivings about Dewitt seeing Epicurean shadows behind every Christian tree, and I do not think Dewitt makes a strong case for the majority of them. I see his reference to the New Testament in that clip for PD14 which instantly makes me suspect. It seems he often went in with an agenda of finding New Testament echoes which makes me suspect of this specific "dynastic" translation then, too.
