2 Chronicles 4 (Cf. 1 Kings 6 and 1 Kings 7)
This chapter is similar to 1 Kings 6 and 7. However, verse one introduces an altar of bronze. It is huge (see photo). The increased size was due to the increased sacrifices being offered.
This passage and the one in 1 Kings 7.23 both describe π quite precisely. Chuck Missler, among others, have commented on this passage. I refer the reader to his article “The Value of Pi.”
