King James Bible Dictionary

A pond, or reservoir, for holding water (Heb. berekhah; modern Arabic, birket), an artificial cistern or tank. Mention is made of the pool of Gibeon (2 Samuel 2:13); the pool of Hebron (4:12); the upper pool at Jerusalem (2 Kings 18:17; 20:20); the pool of Samaria (1 Kings 22:38); the king's pool (Nehemiah 2:14); the pool of Siloah (Nehemiah 3:15; Ecclesiastes 2:6); the fishpools of Heshbon (Song of Solomon 7:4); the "lower pool," and the "old pool" (Isaiah 22:9, 11).

The "pool of Bethesda" (John 5:2, 4, 7) and the "pool of Siloam" (John 9:7, 11) are also mentioned. Isaiah (35:7) says, "The parched ground shall become a pool." This is rendered in the Revised Version "glowing sand," etc. (marg., "the mirage," etc.). The Arabs call the mirage "serab," plainly the same as the Hebrew word sarab, here rendered "parched ground." "The mirage shall become a pool", i.e., the mock-lake of the burning desert shall become a real lake, "the pledge of refreshment and joy." The "pools" spoken of in Isaiah 14:23 are the marshes caused by the ruin of the canals of the Euphrates in the neighbourhood of Babylon.

The cisterns or pools of the Holy City are for the most part excavations beneath the surface. Such are the vast cisterns in the temple hill that have recently been discovered by the engineers of the Palestine Exploration Fund. These underground caverns are about thirty-five in number, and are capable of storing about ten million gallons of water. They are connected with one another by passages and tunnels.

Pools, like the tanks of India, are in many parts of Palestine and Syria the only resource for water during the dry season, and the failure of them involves drought and calamity. (Isaiah 42:15) Of the various pools mentioned in Scripture, perhaps the most celebrated are the pools of Solomon near Bethlehem called by the Arabs el-Burak , from which an aqueduct was carried which still supplies Jerusalem with wafer. (Ecclesiastes 2:6) Ecclus. 24.30, 31.

POOL, noun [Latin palus; Gr. probably from setting, standing, like Latin stagnum, or from issuing, as a spring.]

A small collection of water in a hollow place, supplied by a spring, and discharging its surplus water by an outlet. It is smaller than a lake, and in New England is never confounded with pond or lake. It signifies with us, a spring with a small basin or reservoir on the surface of the earth. It is used by writers with more latitude, and sometimes signifies a body of stagnant water.

POOL

The name given to three large open cisterns at Etam, at the head of the Wady Urtas, having an average length of 400 feet by 220 in breadth, and 20 to 30 in depth. These pools derive their chief supply of water from a spring called "the sealed fountain," about 200 yards to the north-west of the upper pool, to which it is conveyed by a large subterranean passage. They are 150 feet distant from each other, and each pool is 20 feet lower than that above it, the conduits being so arranged that the lowest, which is the largest and finest of the three, is filled first, and then in succession the others. It has been estimated that these pools cover in all a space of about 7 acres, and are capable of containing three million gallons of water. They were, as is generally supposed, constructed in the days of Solomon. They are probably referred to in Ecclesiastes 2:6. On the fourth day after his victory over the Ammonites, etc., in the wilderness of Tekoa, Jehoshaphat assembled his army in the valley of Berachah ("blessing"), and there blessed the Lord. Berachah has been identified with the modern Bereikut, some 5 miles south of Wady Urtas, and hence the "valley of Berachah" may be this valley of pools, for the word means both "blessing" and "pools;" and it has been supposed, therefore, that this victory was celebrated beside Solomon's pools (2 Chronicles 20:26).

These pools were primarily designed to supply Jerusalem with water. From the lower pool an aqueduct has been traced conveying the water through Bethlehem and across the valley of Gihon, and along the west slope of the Tyropoeon valley, till it finds its way into the great cisterns underneath the temple hill. The water, however, from the pools reaches now only to Bethlehem. The aqueduct beyond this has been destroyed.
