Ok, Windmill,
This may seem funny, but it is serious as well, so bear with me.
Now, people use those verses to "prove" the Bible wrong, right? Now, couldn't we also turn that around and say that the Bible proves that pi is wrong?
For that matter, how about we look at the measurement of a "cubit." Now, from my understanding, a cubit is the length of a person's forearm, right? Now, who's forearm would we use? Mine? Yours? The maths teacher's? Now, for a little humor, did you know that your forearm is the same length as your foot? It's true, check it out for yourself if you don't believe me. I got that from a movie...Pretty Woman.... I wouldn't recommend the movie tho.
Now, speaking of feet, how do we know that the current measurements we have are accurate? How do we know an inch is an inch? A foot is a foot? Because my sister measured her foot and it is only 8 inches long. So, how can it be a foot? See, my point is this. People try to trip us up in many ways. As long as we know the truth and hold fast to God, that is what matters.
As far as the measurement of a cubit is concerned, how long is it supposed to be? I mean if we use just anyone's forearm, my sister's cubit would be 8 inches while mine would be 9 maybe 10 inches (because my feet are a little bigger than hers) Do you see what I'm getting at? And for men, it is the same thing. Some men have bigger feet/longer arms than others.
Anyway, as I said in another thread, pi is an evil number that shouldn't be used anyway!
