Do not lose sight of this one thing my friend, a day unto the Lord is as a thousand years; and a thousand years a day.
So HIS definition of a day is obviously subjective.
Physically a day is variable as well. They are not “perfect” 24 hour days, nor were they always this exact length.
Morning and evening of a day without a Sun? Possibly poetic? No way! And Pi is 3. The earth has four corners and does not move. The sky is also solid./s
I know you didn't say that but I didn't know if you were aware of this little tidbit wrt pi in the Bible.
That's as accurate as pi can be written in Hebrew.
