Тосефта к Шофтим 3:8

וַיִּֽחַר־אַ֤ף יְהוָה֙ בְּיִשְׂרָאֵ֔ל וַֽיִּמְכְּרֵ֗ם בְּיַד֙ כּוּשַׁ֣ן רִשְׁעָתַ֔יִם מֶ֖לֶךְ אֲרַ֣ם נַהֲרָ֑יִם וַיַּעַבְד֧וּ בְנֵֽי־יִשְׂרָאֵ֛ל אֶת־כּוּשַׁ֥ן רִשְׁעָתַ֖יִם שְׁמֹנֶ֥ה שָׁנִֽים׃

Посему гнев Господа возгорелся против Израиля, и Он предал их в руки Кушан-Ришатхайма, царя Арам-Нахараимского; и сыны Израилевы служили Кушан-Ришатхайму восемь лет.

Tosefta Sotah

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).
