Pi and the Temple

1 Kings 7:23 describes Solomon’s “molten sea” — a large bronze basin in the Temple:

“He made the Sea of cast metal, circular in shape, measuring ten cubits from rim to rim… It took a line of thirty cubits to measure around it.”

Circumference (30) / Diameter (10) = 3.0 — an approximation of pi (3.14159…). Critics have called this a “biblical error.” But:

• The measurement was of the outer rim (10 cubits) while the circumference may have measured the inner rim (accounting for the handbreadth-thick brim described in v.26)
• Adjusting for the brim: inner diameter ~ 9.55 cubits, giving 30/9.55 = 3.14 — a remarkably accurate value of pi
• The Vilna Gaon (18th-century rabbi) noted that the Hebrew text spells the word for “line” (qav) differently in 1 Kings 7:23 (written קוה) than expected (קו). The gematria ratio of the written form to the expected form = 111/106 = 1.0472. Multiply by 3: 3.1416 — pi to four decimal places, encoded in a spelling anomaly
