This valley clearly defined the Eastern and Western Ridges from each other.
It, too, ran into the Hinnom valley in the south, and provided the western border for the eastern ridge, running parallel to the Kidron, as mentioned above. It is likely the Kidron was 150 - 200 feet below the city, though the valley has been filled with debris over the course of the history of Jerusalem.
The southwestern hill became known as the Upper City.
During Herodian Jerusalem, Herod built his palace in the Upper City.
The Dead Sea, at 1,292 feet below the Mediterranean, is the lowest point on earth and ten miles south of Jericho.
The two cities are separated by a mere 13 miles in distance, yet over 3,500 feet in elevation.
The parable of the Good Samaritan took place on the road between Jerusalem and Jericho.The Western Ridge was actually divided in two by another valley, elevated above the previous three mentioned valleys.This was the Transversal Valley, and divided the southwestern hill from the northeastern hill on the Western Ridge.Jerusalem would eventually come to occupy four hills located on two ridges, the eastern ridge and the western ridge.These two ridges were each flanked by a valley, and separated by another valley as well.
