'Iron' in the Bible

and the people who are in it he hath brought out, and setteth to the saw, and to cutting instruments of iron, and to axes; and thus doth David to all cities of the sons of Ammon, and David turneth back, and all the people, to Jerusalem.

And iron in abundance for nails for leaves of the gates, and for couplings, hath David prepared, and brass in abundance -- there is no weighing.

'And lo, in mine affliction, I have prepared for the house of Jehovah of gold talents a hundred thousand, and of silver a thousand thousand talents; and of brass and of iron there is no weighing, for in abundance it hath been, and wood and stones I have prepared, and to them thou dost add.

To the gold, to the silver, and to the brass, and to the iron, there is no number; arise and do, and Jehovah is with thee.'

and with all my power I have prepared for the house of my God, the gold for things of gold, and the silver for those of silver, and the brass for those of brass, the iron for those of iron, and the wood for those of wood, shoham stones, and settings, and stones of painting and of diverse colours, and all kinds of precious stone, and stones of white marble, in abundance.

And they give for the service of the house of God, of gold -- talents five thousand, and drams a myriad; and of silver -- talents ten thousand, and of brass -- a myriad and eight thousand talents; and of iron -- a hundred thousand talents;
