The Hebrew Old Testament name Cushan is probably a poetic or prolonged name of the land of Cush, the Arabian Cush (). Some have, however, supposed this to be the same as Chushan-Rishathaim (), 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 Ashur-resh-ishi I (the father of Tiglath Pileser I.
The Hebrew Old Testament name Cushan is probably an artistic or elaborate designation for the Arabian land of Cush, whereas some consider it may be identical to Chushan-Rishathaim, with the latter part serving as a title or regional appellation, referring to a Mesopotamian monarch associated with Ashur-resh-ishi I.
