Jerusalem was possessed only of the torrent of Kedron, dry in summer, and of the little spring or brook of Siloe, (Reland, tom. i. p. 294, 300.) Both strangers and natives complain of the want of water, which, in time of war, was studiously aggravated. Within the city, Tacitus mentions a perennial fountain, an aqueduct and cisterns for rain water. The aqueduct was conveyed from the rivulet Tekos or Etham, which is likewise mentioned by Bohadin, (in Vit. Saludio p. 238.)
