1 Chronicles 18:8: “From Tebah and Cun, towns that belonged to Hadadezer, David took a large quantity of bronze. Solomon used it to make the Bronze Sea, the pillars and all the bronze articles.”
1 Kings 7:13-47: “King Solomon sent to Tyre and brought Huram, whose mother was a widow from the tribe of Naphtali and whose father was a man of Tyre skilled in bronze work… He cast two bronze pillars… He also made the Sea of cast metal… It rested on twelve oxen… He made ten stands of bronze; ten bronze basins… pots, shovels and sprinkling bowls. All these objects that Huram made for King Solomon for the temple of the Lord were of burnished bronze… All these things were so numerous that Solomon did not weigh the bronze, for it was beyond measure.”
According to current archaeological findings, there were numerous copper mines in Mesopotamia during Solomon’s time. The amount of copper used by Solomon in building the Temple was immeasurable. Besides the large quantities of copper David acquired during his reign, the abundant copper resources in the surrounding regions during Solomon’s time also provided ample raw materials for the Temple’s construction.
