How Water Tunnels Worked
Jerusalem, Megiddo, Hazor, Gezer and Gibeon all had systems to bring water safely within their city walls during time of siegeCole offers new suggestions on how this technology developed.
A city set on a hill cannot be hidden, said Matthew (5:14). Neither can it easily be supplied with water.
Cities were built on hilltops because of the obvious defensive advantages. These advantages were somewhat offset by the disadvantage that the citys springs or wells were normally at the base of the hill, outside the city walls. As the size of urban populations grew and the height of the cities themselves grew through successive rebuildingscreating higher and higher tellsthe water supply moved progressively farther away.
