L’Ecclésiaste 8:7 Commentaire : Rashi & Tze'enah Ure'enah

For he knows not what will be. When the wicked man sins, he does not give thought that the Holy One, Blessed Is He, is destined to bring him to judgment, and woe is to him because of this.¹⁰Alternatively, man is unable to foresee specific future events. Ibn Ezra

For when it comes to pass. The punishment, “who will tell him,” [i.e.,] to discuss [the matter] with him and to take advice and to ask permission, for it will suddenly befall him.¹¹Alternatively, when a person is about to sin, who will forewarn him of the consequences so that he will be more cautious. (Sforno)

“He does not” [8:7]. When the evildoer commits sins, he does not think about his end, that the Holy One will punish him. Who can advise him how to protect himself when and how the misfortune comes? When it comes, it happens in a moment.¹¹³Rashi, Ecclesiastes, 8:7.
