'Iron' in the Bible

Further, take an iron plate and place it as an iron wall between you and the city, and set your face toward it so that it is under siege, and besiege it. This is a sign to the house of Israel.

“Son of man, the house of Israel has become dross (metallic waste) to Me. All of them are (useless) bronze, tin, iron, and lead in the furnace; they are the dross of silver.

As they gather silver and bronze and iron and lead and tin into the furnace to blow fire on it in order to melt it, so I will gather you in My anger and in My wrath, and I will put you there and melt you.

“Tarshish [in Spain] was your customer and traded with you because of the abundance of your riches of all kinds; with silver, iron, tin, and lead they paid for your wares.

Vedan and Javan traded with yarn from Uzal [in Arabia] for your wares; wrought iron, cassia, and sweet cane were among your merchandise.
