'Iron' in the Bible

for only Og king of Bashan had been left of the remnant of the Rephaim; lo, his bedstead is a bedstead of iron; is it not in Rabbath of the sons of Ammon? nine cubits its length, and four cubits its breadth, by the cubit of a man.

And you hath Jehovah taken, and He is bringing you out from the iron furnace, from Egypt, to be to Him for a people -- an inheritance, as at this day.

a land in which without scarcity thou dost eat bread, thou dost not lack anything in it; a land whose stones are iron, and out of its mountains thou dost dig brass;

even he who cometh in with his neighbour into a forest to hew wood, and his hand hath driven with an axe to cut the tree, and the iron hath slipped from the wood, and hath met his neighbour, and he hath died -- he doth flee unto one of these cities, and hath lived,

and built there an altar to Jehovah thy God, an altar of stones, thou dost not wave over them iron.

And thy heavens which are over thy head have been brass, and the earth which is under thee iron;

thou hast served thine enemies, whom Jehovah sendeth against thee, in hunger, and in thirst, and in nakedness, and in lack of all things; and he hath put a yoke of iron on thy neck, till He hath destroyed thee.

Iron and brass are thy shoes, And as thy days -- thy strength.
