Our Daf ends with a discussion about the sun.
Many rabbis are part of this argument about the healing power of the sun.
Perhaps it is the dust that shines in the rays of the sun;
perhaps it is that righteous people are healed by the sun's light;
perhaps all of us can benefit from the sun's healing power.
And some rabbis believe that the wicked will be punished by the sun's heat.
Reish Lakish states that "in the World to Come, there will be no Gehinom.
Rather, Hashem will remove the sun from its sheath, and the righteous will be healed by it, while the wicked will be punished by it, as it says (Malachi 3:19), 'A sun will come which will burn like a furnace; all the wicked and all the evildoers will be like straw, and the sun will incinerate them.... But a sun of kindness will shine for those who fear Me, with healing in its rays.' Moreover, the righteous will derive pleasure from the sun, as it says (ibid.), '... and you will become sated, as fattened calves entering their pen to feed.'"
We explore the interpretation of the verse in Malachi: ״וְזָרְחָה לָכֶם יִרְאֵי שְׁמִי שֶׁמֶשׁ וְגוֹ׳״ and his prophecy (Steinsaltz) as well as ideas about the messianic era from different perspectives (Rebbe Nachman and Rav Kook).
