As expected, Hazor’s engineers dug this shaft at the southern end of the city, near the freshwater springs that lay nearby, and planned to connect it to a downward sloping tunnel (the photo shows the view looking up the sloping tunnel from below). What was not expected was that the sloping tunnel then turned westward, away from the springs, and ended in a water chamber deep beneath the tell. The water that filled the chamber was sufficient to supply the entire Israelite city without the inhabitants having to risk going outside in times of trouble.
