'Wall' in the Bible

for every high tower, for every fortified wall,

Now I will inform you what I am about to do to my vineyard: I will remove its hedge and turn it into pasture, I will break its wall and allow animals to graze there.

You counted the houses in Jerusalem, and demolished houses so you could have material to reinforce the wall.

So this sin will become your downfall. You will be like a high wall that bulges and cracks and is ready to collapse; it crumbles suddenly, in a flash.

Eliakim, Shebna, and Joah said to the chief adviser, "Speak to your servants in Aramaic, for we understand it. Don't speak with us in the Judahite dialect in the hearing of the people who are on the wall."

But the chief adviser said, "My master did not send me to speak these words only to your master and to you. His message is also for the men who sit on the wall, for they will eat their own excrement and drink their own urine along with you!"

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

I will make your pinnacles out of gems, your gates out of beryl, and your outer wall out of beautiful stones.

We grope along the wall like the blind, we grope like those who cannot see; we stumble at noontime as if it were evening. Though others are strong, we are like dead men.
