'Walls' in the Bible
Now let the king be aware that the Jews who came up to us from you have gone to Jerusalem. They are rebuilding that rebellious and odious city. They are completing its walls and repairing its foundations.
Let the king also be aware that if this city is built and its walls are completed, no more tax, custom, or toll will be paid, and the royal treasury will suffer loss.
We therefore are informing the king that if this city is rebuilt and its walls are completed, you will not retain control of this portion of Trans-Euphrates."
Let it be known to the king that we have gone to the province of Judah, to the temple of the great God. It is being built with large stones, and timbers are being placed in the walls. This work is being done with all diligence and is prospering in their hands.
