'Broken down' in the Bible

I beheld, and, lo, the fruitful field was a wilderness, and all the cities thereof were broken down at the presence of Jehovah, and before his fierce anger.

For thus saith Jehovah, the God of Israel, concerning the houses of this city, and concerning the houses of the kings of Judah, which are broken down to make a defence against the mounds and against the sword;

Of Moab. Thus saith Jehovah of hosts, the God of Israel: Woe unto Nebo! for it is laid waste; Kiriathaim is put to shame, it is taken; Misgab is put to shame and broken down.

Moab is put to shame; for it is broken down: wail and cry; tell ye it by the Arnon, that Moab is laid waste.

How is it broken down! how do they wail! how hath Moab turned the back with shame! so shall Moab become a derision and a terror to all that are round about him.
