Probably an area of the royal estates, situated outside the walls of Jerusalem near the pool of Siloam (2 Kgs 25:4; Jer 39:4; 52:7) in the Kidron Valley, near where the Kidron meets the valley of Hinnom. Upon the return from the exile, Nehemiah set the families to work, each building a part of the wall. Fountain Gate is recorded as being near the pool of Siloam by the king’s garden (Neh 3:15). It is not certain whether the site now called the king’s garden outside the walls of modern Jerusalem is the original site.
