'Wall' in the Bible

Yahweh has purposed to destroy the wall of the daughter of Zion; He has stretched out the line, he has not withdrawn his hand from destroying; He has made the rampart and wall to lament; they languish together.

Their heart cried to the Lord: wall of the daughter of Zion, let tears run down like a river day and night; Give yourself no respite; don't let the apple of your eye cease.
