The City of David
In the ancient pre-Israelite period, the City of David (Holyland) was separated from the Temple Mount by the Ophel, an uninhabited area which became the seat of government under Israelite rule. During the reign of Hezekiah, the walls of the city were expanded westward, enclosing a previously unwalled suburb in the area now known as the Old City of Jerusalem, west of the Temple Mount. 
Pool of Siloam: Siloam is an ancient Greek name derived from the more ancient Hebrew Shiloah. The Arabic: Silwan, was derived form the Greek, Siloam. It is an ancient site in Jerusalem, south of the Old City.

The Siloam inscription was discovered in the water tunnel built during the reign of Hezekiah, in the early 7th Century BC. The Siloam inscription is now preserved in the Archeological Museum of Istanbul, Turkey. King Hezekiah secured the city's water supply against siege by digging the Hezekiah Tunnel through bedrock and covering over all signs of the Gihon Spring and the fortifications that had surrounded it in earlier periods. He built the Pool of Siloam as a water reservoir. Hezekiah then surrounded the new reservoir and the city's burgeoning western suburbs with a new city wall city wall.
