'Iron' in the Bible

And take thou unto thee an iron plate, and put it for a wall of iron between thee and the city; and set thy face against it, and it shall be besieged, and thou shalt lay siege against it: this shall be a sign to the house of Israel.

Son of man, the house of Israel is become dross to me: they are all copper, and tin, and iron, and lead, in the midst of the furnace: they are become the dross of silver.

As they gather silver, and copper, and iron, and lead, and tin, into the midst of the furnace, to blow the fire upon it, to melt it, so will I gather you in mine anger and in my fury, and I will lay you on and melt you.

Tarshish dealt with thee by reason of the abundance of all substance; with silver, iron, tin, and lead, they furnished thy markets.

Vedan and Javan of Uzal traded in thy markets: wrought iron, cassia, and calamus were in thy traffic.
