BETHESDA, JERUSALEM (i.e. "House of Mercy," John v. 2), better perhaps Bethzatha or Bethsaida, a pool or public bath in Jerusalem, where miraculous cures were believed to be performed. The following identifications have been suggested: Birket Isra'il, near St Stephen's gate; a large cistern, near St Anne's church; the "Twin Pools," north of the Haram (the ancient Temple area); the Hammam esh-Shifa' or pool of healing, west of the Haram; the Virgin's fountain, south of the Haram; and the "Pool of Siloam." Which, if any, of these identifications is correct, it is impossible to say.
