'Walls' in the Bible

For the Lord God of hosts has a day of panic and of tumult, of trampling, of confusionIn the Valley of Vision,A [day of] breaking down wallsAnd a crying [for help] to the mountain.

You saw that the breachesIn the wall of the City of David [the citadel of Zion] were many;You collected [within the city’s walls] the waters of the Lower Pool (Siloam).

You also made a reservoir between the two wallsFor the waters of the Old Pool,But you did not look to its Maker,Nor did you recognize Him who planned it long ago.

The high fortifications of your walls He will bring down,Lay low, and cast to the ground, to the dust.

In that day this song will be sung in the land of Judah:“We have a strong city;He sets up salvation as walls and ramparts.

“Indeed, I have inscribed [a picture of] you on the palms of My hands;Your city walls [Zion] are continually before Me.

“And I will make your battlements of rubies,And your gates of [shining] beryl stones,And all your [barrier] walls of precious stones.

To them I will give in My house and within My walls a memorial,And a name better than that of sons and daughters;I will give them an everlasting name which will not be cut off.

“Foreigners will build up your walls,And their kings will serve you;For in My [righteous] wrath I struck you,But in My favor and grace I have had compassion on you.

“Violence will not be heard again in your land,Nor devastation or destruction within your borders;But you will call your walls Salvation, and your gates Praise [to God].

On your walls, O Jerusalem, I have appointed and stationed watchmen (prophets),Who will never keep silent day or night;You who profess the Lord, take no rest for yourselves,
