'Walls' in the Bible

In Your good pleasure, cause Zion to prosper;build the walls of Jerusalem.

day and night they make the rounds on its walls.Crime and trouble are within it;

Why have You broken down its wallsso that all who pass by pick its fruit?

You have broken down all his walls;You have reduced his fortified cities to ruins.

may there be peace within your walls,prosperity within your fortresses.”

Our cattle will be well fed.There will be no breach in the walls,no going into captivity,and no cry of lament in our public squares.
