'Walls of Jerusalem' in the Bible

And I went out by night by the Valley Gate, even before the Jackal Fountain, and to the Dung Gate, and looked at the walls of Jerusalem which were broken down, and its gates which were burned with fire.

And it happened, when Sanballat and Tobiah, and the Arabians, and the Ammonites, and the Ashdodites, heard that the walls of Jerusalem had gone up, and that the breaks were being filled, they were very angry.
