Contradiction with 1 Kings 7:15
In Jeremiah 52:21, the height of the pillars is reported differently from 1 Kings 7:15, where the height of each pillar is described as eighteen cubits, not the thirty-five cubits mentioned in 2 Chronicles 3:15, resulting in an apparent contradiction about the pillar dimensions.
1 Kings 7:15: For he cast two pillars of brass, of eighteen cubits high apiece: and a line of twelve cubits did compass either of them about. [cast: Heb. fashioned]
Paradox #1
Jeremiah 52:21 mentions the height and circumference of pillars. There can be a mathematical inconsistency when calculating the diameter from the given circumference using modern math rules (specifically, the value of pi). The numbers may not align perfectly with today's calculations.
