The “pool of Siloah” lies at the southwestern foot of the temple hill, near the lower end of the Tyropoeon. It appears to have been at all times beyond the line of the city wall, but was perhaps joined to the city by a fortification of its own.
The king’s gardens - See 2 Kings 25:4 note.
The stairs - A flight of steps, still to be seen, led from the low valley of the Tyropoeon up the steep sides of Ophel to the “city of David,” which it reached probably at a point not far south of the temple.
