'Wall' in the Bible

Against every high tower,Against every fortified wall,

“So now let Me tell you what I am going to do to My vineyard:I will remove its hedge and it will be consumed;I will break down its wall and it will become trampled ground.

And you saw that the breachesIn the wall of the city of David were many;And you collected the waters of the lower pool.

Then you counted the houses of JerusalemAnd tore down houses to fortify the wall.

For You have been a defense for the helpless,A defense for the needy in his distress,A refuge from the storm, a shade from the heat;For the breath of the ruthlessIs like a rain storm against a wall.

Therefore this iniquity will be to youLike a breach about to fall,A bulge in a high wall,Whose collapse comes suddenly in an instant,

Then Eliakim and Shebna and Joah said to Rabshakeh, “Speak now to your servants in Aramaic, for we understand it; and do not speak with us in Judean 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, doomed to eat their own dung and drink their own urine with you?”

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

“Moreover, I will make your battlements of rubies,And your gates of crystal,And your entire wall of precious stones.

We grope along the wall like blind men,We grope like those who have no eyes;We stumble at midday as in the twilight,Among those who are vigorous we are like dead men.
