Bible Verses About Walls: Were battered by besieging armies

Yo'av's troops came and put him under siege in Avel of Beit-Ma'akhah - they put up a ramp in the moat against the city wall; and all the people with Yo'av battered the wall in order to bring it down.

Show it under siege - build towers against it, raise earthworks against it, set up camps against it, and surround it with battering rams.

Then take an iron griddle and put it in place as a wall of iron between yourself and the city, and fix your gaze on it - the city is under siege, and you are the one besieging it. This will be a sign for the house of Isra'el.
