Malbim: The Edos that the Torah testified via its tales, that You release Tzadikim from their affliction, is always Tzedek and conducts always.

Radak: I will live forever, in the world to come. "L'Olam" refers also to "v'Echyeh".

Malbim: I request that You make me understand these Edos, so I will understand how You punish Resha'im and save Tzadikim. Often there are perplexities in hidden matters of this conduct, for people see Resha'im succeeding and Tzadikim afflicted.
