'Iron' in the Bible

Only King Og of Bashan remained from the remnants of the Rephaim. In fact, his bed was made of iron. It's in Rabbah of the Ammonites, isn't it? It was nine cubits long and four cubits wide."

a land without scarcity. You'll eat food in it and lack nothing. It's a land where its rocks are iron and you can dig copper from its mountains."

Then build an altar there to the LORD your God, an altar of stones that hasn't been worked with iron tools.

The sky above your head will become bronze while the ground beneath you will become iron.

you'll serve your enemies whom the LORD your God will send against you. You will serve in famine and in drought, in nakedness, and in lack of everything. They'll set a yoke of iron upon your neck until they have exterminated you.

may your bolts be made of iron and bronze, and may your strength be sufficient for each day you live."
