Easton's 1897 Bible Dictionary:

Pool
   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 Sam. 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 (Neh. 2:14); the pool
   of Siloah (Neh. 3:15; Eccles. 2:6); the fishpools of Heshbon
   (Cant. 7:4); the "lower pool," and the "old pool" (Isa.
   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 Isa. 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.


Bouvier's Law Dictionary, Revised 6th Ed (1856):

POOL. A small lake of standing water.
     2. By the grant of a pool, it is said, both the land and water will
pass. Co. Litt. 5. Vide Stagnum; Water. Undoubtedly the right to fish, and
probably the right to use hydraulic works, will be acquired by such grant. 2
