'Iron' in the Bible

And take thou unto thee an iron pan, and set it for a wall of iron between thee and the city: and set thy face toward 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 unto me: all of them are brass and tin and iron and lead, in the midst of the furnace; they are the dross of silver.

As they gather silver and brass 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 wrath, and I will lay you there, and melt you.

Tarshish was thy merchant by reason of the multitude of all kinds of riches; with silver, iron, tin, and lead, they traded for thy wares.

Vedan and Javan traded with yarn for thy wares: bright iron, cassia, and calamus, were among thy merchandise.
