'Iron' in the Bible

And thou, take to thee an iron pan, and thou hast made it a wall of iron between thee and the city; and thou hast prepared thy face against it, and it hath been in a siege, yea, thou hast laid siege against it. A sign it is to the house of Israel.

The house of Israel hath been to Me for dross, All of them are brass, and tin, and iron, and lead, In the midst of a furnace -- dross hath silver been,

A gathering of silver, and brass, and iron, and lead, and tin, Unto the midst of a furnace -- to blow on it fire, to melt it, So do I gather in Mine anger and in My fury, And I have let rest, and have melted you.

Tarshish is thy merchant, Because of the abundance of all wealth, For silver, iron, tin, and lead, They have given out thy remnants.

Vedan and Javan go about with thy remnants, They have given shining iron, cassia, and cane, In thy merchandise it hath been.
