'Stones' in the Bible

a land where you will eat food without scarcity, in which you will not lack anything; a land whose stones are iron, and out of whose hills you can dig copper.

So it shall be on the day when you cross the Jordan to the land which the Lord your God gives you, that you shall set up for yourself large stones and coat them with lime

So it shall be when you cross the Jordan, you shall set up on Mount Ebal, these stones, as I am commanding you today, and you shall coat them with lime.

Moreover, you shall build there an altar to the Lord your God, an altar of stones; you shall not wield an iron tool on them.

You shall build the altar of the Lord your God of uncut stones, and you shall offer on it burnt offerings to the Lord your God;

You shall write on the stones all the words of this law very distinctly.”
