תּוספֿתּא אויף שופטים 3:8

As long as Joshua and the Elders were alive, there did not exist among the Children of Israel anyone who called upon [idols], and idol worshippers never did damage to the Israelites, as it is said (Judges 2:7), "And the people served God all the days of Joshua and all the days of the Elders who continued living after Joshua." Once Joshua and the Elders died, what does it say, but (Judges 3:8), "And the Children of Israel served Cushan-Rishataim [the King of Aram] for eight years." Why was his name "Rishataim" (literally, "twice evil")? Because he performed two evil deeds. First, he subjugated Israel, and second, he desecrated his oath (see Sanh. 105a:8).
