REZEPH.—A city mentioned in the message of the Rabshakeh of Sennacherib to Hezekiah (2Ki_19:12, Isa_37:12). It is the Ratsappa or Ratsapi of the Assyrian inscriptions, the modern Rasafa, between Palmyra and the Euphrates. This district belonged for several centuries to the Assyrians, and many of the tablets show it to have been an important trade-centre. Between b.c. 839 and 737 the prefects who had authority in the place were, to all appearance, Assyrians, only one, of unknown but apparently late date, having a name which may be West Semitic, namely, Abda’, possibly a form of ‘Abda or ‘Obadiah.
