'Stones' in the Bible

a land where you may eat food in plenty and find no lack of anything, a land whose stones are iron and from whose hills you can mine copper.

When you cross the Jordan River to the land the Lord your God is giving you, you must erect great stones and cover them with plaster.

So when you cross the Jordan you must erect on Mount Ebal these stones about which I am commanding you today, and you must cover them with plaster.

Then you must build an altar there to the Lord your God, an altar of stones -- do not use an iron tool on them.

You must build the altar of the Lord your God with whole stones and offer burnt offerings on it to the Lord your God.

You must inscribe on the stones all the words of this law, making them clear."
