'Copper' in the Bible

a land where you may eat food in plenty and find no lack of anything, a land whose stones are iron and from whose hills you can mine copper.

Iron is taken from the ground, and rock is poured out as copper.

Set the empty pot on the coals, until it becomes hot and its copper glows, until its uncleanness melts within it and its rot is consumed.

Do not take gold, silver, or copper in your belts,

And a poor widow came and put in two small copper coins, worth less than a penny.

He also saw a poor widow put in two small copper coins.
