פּירוש אויף קהלת 2:12

“And I turned” [2:12]. I will turn away from all these deeds and will study Torah and the punishments for the transgressions so that the Holy One should not issue an evil decree against me. When the decree goes forth from the Holy One, no pleading helps. Therefore, I want to see ahead so that it should not come to a decree from the Holy One.²⁴Rashi, Ecclesiastes, 2:12.

I [then] turned my attention to behold wisdom. I turn away from all my affairs to delve into Torah, and madness and folly, [i.e.,] the punishment for transgressions.

For what value is the man who would come after the king. To supplicate him concerning a decree that they decreed upon him, and they already executed the decree and it is already in effect. It is better for him to consider at first his actions, and he would not find it necessary for him to appeal.
