Cushan
    probably a poetic or prolonged name of the land of Cush, the
    Arabian Cush (Hab. 3:7). Some have, however, supposed this to be
    the same as Chushan-rishathaim (Judg. 3:8, 10), i.e., taking the
    latter part of the name as a title or local appellation, Chushan
    "of the two iniquities" (= oppressing Israel, and provoking them
    to idolatry), a Mesopotamian king, identified by Rawlinson with
    Asshur-ris-ilim (the father of Tiglathpileser I.); but
    incorrectly, for the empire of Assyria was not yet founded. He
    held Israel in bondage for eight years.
