'Iron' in the Bible

All the silver and gold, as well as bronze and iron items, belong to the Lord. They must go into the Lord's treasury."

But they burned the city and all that was in it, except for the silver, gold, and bronze and iron items they put in the treasury of the Lord's house.

just as Moses the Lord's servant had commanded the Israelites. As described in the law scroll of Moses, it was made with uncut stones untouched by an iron tool. They offered burnt sacrifices on it and sacrificed tokens of peace.

saying, "Take home great wealth, a lot of cattle, silver, gold, bronze, iron, and a lot of clothing. Divide up the goods captured from your enemies with your brothers."
