'Wall' in the Bible

and upon every lofty tower, and upon every fortified wall,

And now I will tell you what I will do to my vineyard: I will take away the hedge thereof, and it shall be eaten up; I will break down the wall thereof, and it shall be trodden down:

and ye numbered the houses of Jerusalem, and ye brake down the houses to fortify the wall;

For thou hast 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 terrible ones is as a storm against the wall.

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

Then said Eliakim and Shebna and Joah unto Rabshakeh, Speak, I pray thee, unto thy servants in the Syrian language; for we understand it: and speak not to us in the Jews language, in the ears of the people that are on the wall.

But Rabshakeh said, Hath my master sent me to thy master, and to thee, to speak these words? hath he not'sent me to the men that sit upon the wall, to eat their own dung, and to drink their own water with you?

Then Hezekiah turned his face to the wall, and prayed unto Jehovah,

We grope for the wall like the blind; yea, we grope as they that have no eyes: we stumble at noonday as in the twilight; among them that are lusty we are as dead men.
