Now Jericho was shut up because of the children of Israel (Joshua 6:1).
Jericho is located in the flat Jordan Valley plain just to the east of the Judean hills. The ancient city was built next to a large spring (known today as “Elisha’s Spring”), which was key to the survival of the city over the millennia. Located 820 feet (250 m) below sea level, Jericho is the lowest city on the surface of the earth. Rainfall averages 5.5 inches (140 mm) per year, although in some years there is virtually none.
