'Walls of Jerusalem' in the Bible

Then I said to them, "You see the misery that we are in, that Jerusalem is ruined and its gates burned by the fire. Come, build the walls of Jerusalem and we shall no longer be a disgrace."

Now when Sanballat, Tobiah, the Arabs, the Ammonites, and the Ashdodites heard that the restoration of the walls of Jerusalem were going forward and the gaps were being closed, they were very angry.
