'Wall' in the Bible

For every lofty tower, for every fortified wall,

Now I will tell you what I will do to my vineyard. I will take away its hedge, and it will be eaten up. I will break down its wall of it, and it will be trampled down.

You numbered the houses of Jerusalem, and you broke down the houses to fortify the wall.

For you have been a stronghold to the poor, a stronghold to the needy in his distress, a refuge from the storm, a shade from the heat, when the blast of the dreaded ones is like a storm against the wall.

therefore this iniquity shall be to you like a breach ready to fall, swelling out in a high wall, whose breaking comes suddenly in an instant.

Then Eliakim, Shebna and Joah said to Rabshakeh, "Please speak to your servants in Aramaic, for we understand it; and don't speak to us in the Jews' language in the hearing of the people who are on the wall."

But Rabshakeh said, "Has my master sent me only to your master and to you, to speak these words, and not to the men who sit on the wall, who will eat their own dung and drink their own urine with you?"

Then Hezekiah turned his face to the wall and prayed to Yahweh,

We grope for the wall like the blind; yes, we grope as those who have no eyes: we stumble at noonday as in the twilight; among those who are lusty we are as dead men.
