עַל־כֵּ֤ן ׀ לֹא־יָקֻ֣מוּ רְ֭שָׁעִים בַּמִּשְׁפָּ֑ט וְ֝חַטָּאִ֗ים בַּעֲדַ֥ת צַדִּיקִֽים׃
דרום װעלן די רשָעים ניט באַשטײן פֿאַרן משפּט, און די זינדיקע אין דער עדה פֿון די צדיקים,
Radak
Therefore wicked men shall not rise up: – Therefore, since the wicked walk in an evil way in this world, they shall not rise up in the Judgment: He means to say, in the Day of Judgment, and that is the day of death, they shall have no rising again.
Ibn Ezra
Therefore (עַל־כֵּן - al ken): This refers back [to the previous verse, indicating the consequence of being like chaff]: that the souls of the wicked will perish, and the memory of their descendants in this world [will also perish]. Therefore, the word "will not stand" (lo yakumu) means they will not endure (ya'amdu).
