'Copper' in the Bible

a land where you will eat food without shortage, where you will lack nothing; a land whose rocks are iron and from whose hills you will mine copper.

Iron is taken from the ground,and copper is smelted from ore.

“Son of man, the house of Israel has become dross to Me. All of them are copper, tin, iron, and lead inside the furnace; they are the dross of silver.

Just as one gathers silver, copper, iron, lead, and tin into the furnace to blow fire on them and melt them, so I will gather you in My anger and wrath, put you inside, and melt you.

Set the empty pot on its coalsso that it becomes hot and its copper glows.Then its impurity will melt inside it;its rust will be consumed.

Don’t take along gold, silver, or copper for your money-belts.

When they come from the marketplace, they do not eat unless they have washed. And there are many other customs they have received and keep, like the washing of cups, jugs, copper utensils, and dining couches.)
