If God doesn't take unnecessary steps, why bother with a diameter measurement? You know the thickness of the pot, after all, so you could have calculated the diameter.
If your answer is that humans were doing it, and humans do take unnecessary steps, than I am back to my original question: which parts of the bible are, actually, infallble moral guides, and which are just describing fallible human behavior? And if we're going back to that, than I'll remind you that I still don't seem to have an answer to the question of whether the Golden Rule prevails over a Commandment or vice versa?
True, he didn't need to bother to include it ..... unless God considered it a necessary step to provide enough information such that skeptics could confirm the veracity of the text.
I haven't forgotten your question - as I said earlier, it's complicated because I don't think the question can be answered without making it a long essay that adequately provides the background and justification for the answer. Time is a problem for me right now as I'm taking a few days of vacation with out of town visitors but sometime when I get a chance I'll tackle it.
