יִ֠תְבָּֽרֲרוּ וְיִֽתְלַבְּנ֤וּ וְיִצָּֽרְפוּ֙ רַבִּ֔ים וְהִרְשִׁ֣יעוּ רְשָׁעִ֔ים וְלֹ֥א יָבִ֖ינוּ כָּל־רְשָׁעִ֑ים וְהַמַּשְׂכִּלִ֖ים יָבִֽינוּ׃
Many shall purify themselves, and make themselves white, and be refined; but the wicked shall do wickedly; and none of the wicked shall understand; but they that are wise shall understand.
Rashi on Daniel
They will be clarified and whitened [i.e.,] these calculations.
Rashi on Daniel
and...will be purified [i.e.,] many [will be purified] by them to understand them.
Rashi on Daniel
and the wicked will pervert the calculations by computing them incorrectly, and when they terminate, they will say that there is no more redemption.
