What does 2 Kings 3:25 mean?

And they beat down the cities; and on every good piece of land they cast every man his stone, and filled it; and they stopped all the fountains of water, and felled all the good trees, until in Kir-hareseth only they left the stones thereof; howbeit the slingers went about it, and smote it.

And they beat down the cities, and on every good piece of land cast every man his stone, and filled it; and they stopped all the wells of water, and felled all the good trees: only in Kir–haraseth left they the stones thereof; howbeit the slingers went about it, and smote it.

Pulling down the towns, covering every good field with stones, stopping up all the water-springs, and cutting down all the good trees; they went on driving Moab before them till only in Kir-hareseth were there any Moabites; and the fighting-men went round the town raining stones on it.

and the cities they break down, and <FI>on<Fi> every good portion they cast each his stone, and have filled it, and every fountain of water they stop, and every good tree they cause to fall--till one had left its stones in Kir-Haraseth, and the slingers go round and smite it.

And they destroyed the cities: And they filled every goodly field, every man casting his stone: and they stopt up all the springs of waters: and cut down all the trees that bore fruit, so that brick walls only remained: and the city was beset by the slingers, and a great part thereof destroyed.

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.
