[PatrickHenry]

Mystery Solved, the ancient people did have an understanding of PI. In fact, there is no way other than as done in the scriptures, where someone can give two even measurements of the sea and do it with economy of language (using the figures of 30 and 10 cubits to describe all the measurements of the molten sea).

That's the usual way of "saving" the passage. It would have been more economical to say it was 10 cubits across, period. If they knew about pi, there was absolutely no need to mention the circumfrence. The diameter alone was all that was needed to convey that information.

They could have also specifically mentioned the thickness of the pond if they wanted to, directly, without all the fudging around, but it's difficult to divine that such was the purpose of what was actually stated. Anyway, whatever it was, it's gone now. I don't worry much about it.
