What do we learn from "Tenu Shechar l'Oved"?
Sanhedrin 43a: Before executing someone, we give to him a cup of wine 1 with frankincense inside (to befuddle him 2 ).
Eruvin 65a: Wine was created only [to console mourners, and] to give to Resha'im their reward in this world.
Rashi: Oved is one who will perish in the end, i.e. a Rasha.
Malbim: Shechar, which intoxicates, is proper only for Oved, so he will mind will be totally perturbed and "he will forget his poverty" (7), just like we intoxicate one who goes to be executed.
Why does it say "v'Yayin l'Marei Nafesh"?
Eruvin 65a: Wine was created only to console mourners [and to give to Resha'im their reward in this world].
Rashi: Marei Nafesh are those who are pained over their poverty and mourning.
Malbim: To bitter people we give wine, which gladdens the heart, "so he will not recall all his toil" (7).
