According to biblical sources, Chushan-Rishathaim (Hebrew: כּוּשַׁן רִשְׁעָתַיִם Ḵūšān Riš‘āṯayim, "twice-evil Kushite") was king of Aram-Naharaim, or Northwest Mesopotamia, and the first oppressor of the Israelites after their settlement in Canaan. In the Book of Judges, God delivers the Israelites into his hand for eight years (Judges 3:8) as a punishment for polytheism. However, when the people of Israel "cried out to the Lord", He saved them through Othniel, son of Kenaz (Judges 3:9).
'Cushan' or 'Chushan' may indicate Cushite origins. 'Rishathaim' means 'double-wickedness'.
