CISTERN (Heb. bō’r or bôr). An artificial tank or reservoir dug in the earth or rock for the collection and storage of rain water, or, sometimes, of spring water brought from a distance by a conduit. A cistern is distinguished from a pool by always being covered. Cisterns were very numerous in Palestine. The long, dry, rainless summers, lasting from May to September, and the small annual precipitation, together with a lack of natural springs, made the people largely dependent on rain water. Cisterns were fed from surface and roof drainage by gutters and pipes. The hilly character of the land allowed little rain to penetrate the soil. Most of it flowed down the steep hillsides through the many ravines and watercourses, and it was easily brought by conduits to pools and cisterns. Cisterns in Palestine varied in size and character. Some were cut wholly in the rock, often in the form of a bottle-shaped tank, with a long stairway leading to the surface of the ground. They were often of great depth, some more than one hundred feet (thirty-one m.) deep. Very large ones were supported by rock pillars. The temple area in Jerusalem had at least thirty-seven great cisterns, one of them holding between two and three million gallons (8 and 11 million liters). Public rock-cut cisterns were made within the city walls so that the inhabitants could hold out in time of siege.
Where the substratum of the soil was earth and not rock, cisterns of masonry were built. Some of these were large and had vaulted roofs supported by pillars. Besides the large public cisterns, there were many smaller private ones. Ancient sites are honeycombed with them. All cisterns had one or more openings for drawing water to the surface. They needed periodic cleaning because of the impurities washed in from the outside. Empty cisterns were sometimes used as prisons. Joseph was cast into one (
Existing cisterns were to be taken over by the Hebrews in the Conquest (
Examples of complex cistern construction from Biblical times occur at Jerusalem, Samaria, Mareshah, Masada, and other sites. The cistern or well was a domestic gathering place and center of life in the Near E, and sometimes the object of strife. Many of those from ancient times are still in daily use.

Use of Terms:
"Cistern," bo’r (
The efforts made to supplement the natural water supply, both in agricultural and in populated areas, before as well as after the Conquest, are clearly seen in the innumerable cisterns, wells and pools which abound throughout Palestine The rainy season, upon which the various storage systems depend, commences at the end of October and ends in the beginning of May. In Jerusalem, the mean rainfall in 41 years up to 1901 was 25,81 inches, falling in a mean number of 56 days (see Glaisher, Meteorological Observations, 24). Toward the end of summer, springs and wells, where they have not actually dried up, diminish very considerably, and cisterns and open reservoirs become at times the only sources of supply. Cisterns are fed from surface and roof drainage. Except in the rare instances where springs occur, wells depend upon percolation. The’ great open reservoirs or pools are fed from surface drainage and, in some cases, by aqueducts from springs or from more distant collecting pools. In the case of private cisterns, it is the custom of the country today to close up the inlets during the early days of the rain, so as to permit of a general wash down of gathering surfaces, before admitting the water. Cisterns, belonging to the common natives, are rarely cleansed, and the inevitable scum which collects is dispersed by plunging the pitcher several times before drawing water. When the water is considered to be bad, a somewhat primitive cure is applied by dropping earth into the cistern, so as to sink all impurities with it, to the bottom. The accumulation often found in ancient cisterns probably owes some of its presence to this same habit.
2. Wells or Cylindrical Cisterns:
It is necessary to include wells under the head of cisterns, as there appears to be some confusion in the use of the two terms. Wells, so called, were more often deep cylindrical reservoirs, the lower part of which was sunk in the rock and cemented, the upper part being built with open joints, to receive the surface percolation. They were often of great depth. Job’s well at Jerusalem, which is certainly of great antiquity, is 125 ft. deep (seeFund, "Jerus," 371).
3. Private Cisterns:
Private cisterns must be distinguished from public cisterns or wells. They were smaller and were sunk in the rocks within private boundaries, each owner having his own cistern (
4. Public Cisterns:
Besides private cisterns there were huge public rock-cut cisterns within the city walls. The great water caverns under the Temple area at Jerusalem show a most extensive system of water storage (see Recovery of Jerusalem, chapter vii). There are 37 of these described in Palestine Exploration Fund, "Jerus," 217 ff, and the greatest is an immense rock-cut cavern the roof of which is partly rock and partly stone, supported by rock piers (see Fig. 1, Palestine Exploration Fund). It is 43 ft. deep with a storage capacity of over two million gallons and there are numerous access manholes. This cistern is fed by an aqueduct from Solomon’s Pools about 10 miles distant by road, and is locally known as Bahar el Kebir, the "Great Sea." One of the most recent and one of the most interesting rock-cut reservoirs yet discovered is that at Gezer. (See Palestine Exploration Fund Statement, 1908, 96 ff.) In this example, the pool of spring water is reached by a great rock-tunnel staircase which descends 94 ft. 6 inches from the surface. The staircase diminishes in size as it descends, and at its greatest, it is 23 ft. high and 12 ft. 10 inches wide. These proportions may seem unnecessarily large, but may be accounted for by the necessity for providing light at the water level. As a matter of fact, the brink of the pool receives the light from above. The work dates back to pre-Israelite times.
5. Pools and Aqueducts:
Open pools were common in every city. They were cut out of the rock and were built and cemented at points where occasion demanded. They were often of great size. The pool outside Jerusalem known as Birket es Sultan measures 555 ft. x 220 ft. x 36 ft. deep, and the so-called Hezekiah’s Pool within the walls, is 240 ft. x 144 ft. x about 20 ft. deep. The latter probably owes its origin to the rock-cut fosse of early Jewish date. The Birket es Sultan, on the other hand, probably dates from the time of the Turkish occupation. They may, however, be taken as examples, which, if somewhat larger, are still in accord with the pool system of earlier history. Pools were usually fed by surface drainage, and in some cases by aqueducts from springs at some distance away. They seem to have been at the public service, freely accessible to both man and beast. Pools situated outside the city walls were sometimes connected by aqueducts with pools within the city, so that the water could be drawn within the walls in time of siege. The so-called
Herod embellished the upper pool, lining it with stone and building arches around its four sides (see Palestine Exploration Fund, Excavations at Jerusalem, 154 ff), and the pool was most likely in this condition in the time of Christ (
