וּבָעִתִּ֣ים הָהֵ֔ם רַבִּ֥ים יַֽעַמְד֖וּ עַל־מֶ֣לֶךְ הַנֶּ֑גֶב וּבְנֵ֣י ׀ פָּרִיצֵ֣י עַמְּךָ֗ יִֽנַּשְּׂא֛וּ לְהַעֲמִ֥יד חָז֖וֹן וְנִכְשָֽׁלוּ׃
Rashi on Daniel
and the sons of the renegades of your people will exalt themselves to bring about the vision I saw in the name of Rav Saadia Gaon that they were the renegades of Israel and their company.
