Pi & the Bible

Who likes Pie?

Of course in this case I am talking about the Math version.

Pi is always the Circumference divided by the diameter.  The older way to say it is Pi is the Circumference divided by the Radius squared.  Pi is interesting since it is an irrational number, so it never repeats.  

Back in 8th grade when I in Math class the teacher mentioned Pi was in the Bible.  Hearing someone mention the Bible in school, shocked me so much I almost fell off my chair. 

When I was researching the Fibonacci sermon I presented in 2014, I thought about Pi and looked it up too, and this is what I found.


1 Kings 7:23, 26a

Now he made the sea of cast metal ten cubits from brim to brim, circular in form, and its height was five cubits, and thirty cubits in circumference.

It was a handbreadth thick,

For the Math piece now:

If eighteen inches is one cubit
And one handbreadth is 4 inches

outer diameter: 10 cubits, or 180 inches
inner circumference: 30 cubits, or 540 inches

Inner diameter:
(outer diameter – each side handbreadth)
180 – 8 = 172 inches

inner diameter:  172 inches
inner circumference:  540 inches

The circumference formula is C / D = π,
which gives us:

540 / 172 = π
π =  540/172  = 3.13953488..., about 3.14


Pretty close to PI for using measurements of handbreadths which are not as fine a measurement as we use today.

To sum up, measurements in the Bible can be used to approximate pi, but it isn’t exactly stated either.

Isn’t it interesting that when science catches up and we discover pi, we find out it was in the Bible the whole time.


I almost fell out of my chair since I wasn’t ready to hear a mention about the Bible, which was not a good thing, we are warned to always be alert in 1 Peter 1:13:

Therefore, prepare your minds for action, keep sober in spirit, fix your hope completely on the grace to be brought to you at the revelation of Jesus Christ

and 1 Peter 5:10:

Be of sober spirit, be on the alert. Your adversary, the devil, prowls around like a roaring lion, seeking someone to devour.

Wherever we might go or study, we should have our minds attuned to God.
