'Iron' in the Bible

And take for yourself a plate of iron, and you must place it [as] a wall of iron between you and the city, and you must set your face against it, and it must be {under siege}, and you must lay the siege against it; it is a sign for the house of Israel.

"Son of man, the house of Israel has become as silver dross to me; all of them [are as] bronze and tin and iron and lead in the midst of a furnace, [even] [as] silver dross, silver [dross] they became!

like the gathering of silver and bronze and iron and lead and tin to the middle of a furnace to blow fire on it for melting. Thus I will gather in my anger and in my rage, and I will {deposit} you, and I will melt you.

" 'Tarshish [was] your trader; from [the] abundance of all of [their] wealth, with silver, iron, tin, and lead they exchanged for your merchandise.

Vedan and Javan from Uzal, they exchanged wrought iron, cinnamon, and reed spice for your merchandise; [all this] was for your wares.
