Easton's 1897 Bible Dictionary:

Fountain
(Heb. 'ain; i.e., "eye" of the water desert), a natural source
of living water. Palestine was a "land of brooks of water, of
fountains, and depths that spring out of valleys and hills"
(Deut. 8:7; 11:11).

  These fountains, bright sparkling "eyes" of the desert, are
remarkable for their abundance and their beauty, especially on
the west of Jordan. All the perennial rivers and streams of the
country are supplied from fountains, and depend comparatively
little on surface water. "Palestine is a country of mountains
and hills, and it abounds in fountains of water. The murmur of
these waters is heard in every dell, and the luxuriant foliage
which surrounds them is seen in every plain." Besides its
rain-water, its cisterns and fountains, Jerusalem had also an
abundant supply of water in the magnificent reservoir called
"Solomon's Pools" (q.v.), at the head of the Urtas valley,
whence it was conveyed to the city by subterrean channels some
10 miles in length. These have all been long ago destroyed, so
that no water from the "Pools" now reaches Jerusalem. Only one
fountain has been discovered at Jerusalem, the so-called
"Virgins's Fountains," in the valley of Kidron; and only one
well (Heb. beer), the Bir Eyub, also in the valley of Kidron,
south of the King's Gardens, which has been dug through the
solid rock. The inhabitants of Jerusalem are now mainly
dependent on the winter rains, which they store in cisterns.
