Chushan-rishathaim
    Cush of double wickedness, or governor of two presidencies, the
    king of Mesopotamia who oppressed Israel in the generation
    immediately following Joshua (Judg. 3:8). We learn from the
    Tell-el-Amarna tablets that Palestine had been invaded by the
    forces of Aram-naharaim (A.V., "Mesopotamia") more than once,
    long before the Exodus, and that at the time they were written
    the king of Aram-naharaim was still intriguing in Canaan. It is
    mentioned among the countries which took part in the attack upon
    Egypt in the reign of Rameses III. (of the Twentieth Dynasty),
    but as its king is not one of the princes stated to have been
    conquered by the Pharaoh, it would seem that he did not actually
    enter Egypt. As the reign of Rameses III. corresponds with the
    Israelitish occupation of Canaan, it is probable that the
    Egyptian monuments refer to the oppression of the Israelites by
    Chushan-rishathaim. Canaan was still regarded as a province of
    Egypt, so that, in attacking it Chushan-rishathaim would have
    been considered to be attacking Egypt.
