'Iron' in the Bible

and all the silver and gold, and vessels of brass and iron, holy they are to Jehovah; into the treasury of Jehovah they come.'

And the city they have burnt with fire, and all that is in it; only, the silver and the gold, and the vessels of brass, and of iron, they have given to the treasury of the house of Jehovah;

as Moses, servant of Jehovah, commanded the sons of Israel, as it is written in the book of the law of Moses -- an altar of whole stones, over which he hath not waved iron -- and they cause to go up upon it burnt-offerings to Jehovah, and sacrifice peace-offerings;

And the sons of Joseph say, 'The hill is not found to us, and a chariot of iron is with every Canaanite who is dwelling in the land of the valley -- to him who is in Beth-Shean and its towns, and to him who is in the valley of Jezreel.'

because the mountain is thine; because it is a forest -- thou hast prepared it, and its outgoings have been thine; because thou dost dispossess the Canaanite, though it hath chariots of iron -- though it is strong.'

and Iron, and Migdal-El, Horem, and Beth-Anath, and Beth-Shemesh; nineteen cities and their villages.

and speak unto them, saying, 'With great riches turn ye back unto your tents, and with very much cattle, with silver, and with gold, and with brass, and with iron, and with very much raiment; divide the spoil of your enemies with your brethren.'
