'Bronze' in the Bible

From Betah and from Berothai, cities of Hadadezer, King David took a very large amount of bronze.

Toi sent Joram his son to King David to greet him and bless him, because he had fought against Hadadezer and defeated him; for Hadadezer had been at war with Toi. And Joram brought with him articles of silver, of gold and of bronze.

Then Ishbi-benob, who was among the descendants of the giant, the weight of whose spear was three hundred shekels of bronze in weight, was girded with a new sword, and he intended to kill David.

“He trains my hands for battle,So that my arms can bend a bow of bronze.
