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.
