2 Kings 3:25

And they beat down the cities
Demolished the walls of them, and houses in them, wherever they came:

and on every good piece of land cast every man his stone, and filled
it;
which they had taken out of the walls and houses they pulled down; or which they picked up in the highway, as they passed along, being a stony country; or which being laid in heaps, gathered out of the fields, they took and scattered them all over them:

and they stopped all the wells of water;
with stones and dirt:

and felled all the good trees;
fruit bearing ones; (See Gill on 2 Kings 3:19),

only in Kirharaseth left they the stones thereof;
not able to demolish it, it being a strong fortified city, the principal of the kingdom, and into which the king of Moab had thrown himself, and the remains of his forces; of which see ( Isaiah 16:7 Isaiah 16:10 ) ,

howbeit, the slingers went about it, and smote it;
smote the soldiers that appeared upon the walls of it; though Kimchi, and other Jewish writers, understand it of engineers, who cast out large stones from a sort of machines then in use, to batter down and break through the walls of cities.
