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.
I see the tents of cushan in affliction; The curtains of the land of Midian do tremble.
The district of Goshen was indeed the nome of cushan; but the two words are not of the same purport.
Then, having gathered an army fit for his purpose, he was not long in sweeping the garrisons of cushan out of the land.
We can suppose that the pressure of this rising empire was one cause of the expedition of cushan towards the western sea.
