'Stones' in the Bible

And ye shall smite every fortified city, and every choice city, and shall fell every good tree, and stop all wells of water, and mar every good piece of land with stones.

And they beat down the cities, and on every good piece of land cast every man his stone and filled it, and they stopped every well of water, and felled every good tree, until they left only the stones at Kirhareseth; and the slingers went about it, and smote it.
