'Iron' in the Bible

And he took the people out of the town and put them to work with wood-cutting instruments, and iron grain-crushers, and axes. And this he did to all the towns of the children of Ammon. Then David and all the people went back to Jerusalem.

And he got together a great store of iron, for the nails for the doors and for the joins; and brass, more in weight than might be measured;

Now see, poor though I am, I have got ready for the house of the Lord a hundred thousand talents of gold and a million talents of silver; and a weight of brass and iron greater than may be measured; and wood and stone have I made ready, and you may put more to it.

In gold and silver and brass and iron more than may be numbered. Up! then, and to work; and may the Lord be with you.

Now as far as I am able, I have made ready what is needed for the house of my God; the gold for the things of gold, and the silver for the silver things, and the brass for the brass things, iron for the things of iron, and wood for the things of wood; beryls and jewels to be framed, and stones of different colours for ornament; all sorts of stones of great price, and polished building-stone, as much as is needed and more.

And they gave for the use of the house of the Lord, five thousand talents and ten thousand darics of gold, and ten thousand talents of silver, and eighteen thousand talents of brass, and a hundred thousand talents of iron.
