The Gemara relates that the tanna who recited mishnayot and baraitot in the study hall taught a baraita before Rav Naḥman bar Yitzḥak: Anyone who humiliates another in public, it is as though he were spilling blood. Rav Naḥman bar Yitzḥak said to him: You have spoken well, as we see that after the humiliated person blushes, the red leaves his face and pallor comes in its place, which is tantamount to spilling his blood. Abaye said to Rav Dimi: In the West, i.e., Eretz Yisrael, with regard to what mitzva are they particularly vigilant? Rav Dimi said to him: They are vigilant in refraining from humiliating others, as Rabbi Ḥanina says: Everyone descends to Gehenna except for three. The Gemara asks: Does it enter your mind that everyone descends to Gehenna? Rather, say: Anyone who descends to Gehenna ultimately ascends, except for three who descend and do not ascend, and these are they: One who engages in intercourse with a married woman, as this transgression is a serious offense against both God and a person; and one who humiliates another in public; and one who calls another a derogatory name. The Gemara asks with regard to one who calls another a derogatory name: That is identical to one who shames him; why are they listed separately? The Gemara answers: Although the victim grew accustomed to being called that name in place of his name, and he is no longer humiliated by being called that name, since the intent was to insult him, the perpetrator’s punishment is severe. Rabba bar bar Ḥana says that Rabbi Yoḥanan says: [59a] It is preferable for a person to engage in intercourse with a woman whose married status is uncertain and not humiliate another in public. The Gemara asks: From where do we derive this? The Gemara answers: It is from that which Rava interpreted, as Rava interpreted: What is the meaning of that which is written: “And when I limped they rejoiced and gathered…they tore and did not cease [damu]” (Psalms 35:15)? The term “damu” can also be understood as a reference to blood. Concerning the fasting he undertook to atone for his sin with Bathsheba (see II Samuel, chapters 11–12), David said before the Holy One, Blessed be He: Master of the Universe, it is revealed and known before You that if my tormenters were to tear my flesh, my blood [dami] would not flow to the ground, due to excessive fasting. And moreover, they torment me to the extent that even at the time when they are engaged in the public study of the halakhot of leprous sores and tents in which there is a corpse, i.e., halakhic matters that have no connection to my sin, they say to me: David, one who engages in intercourse with a married woman, his death is effected with what form of execution? And I say to them: One who engages in intercourse with a married woman before witnesses and with forewarning, his death is by strangulation, but he still has a share in the World-to-Come. But one who humiliates another in public has no share in the World-to-Come. The transgression of you, who humiliate me, is more severe than my transgression. And Mar Zutra bar Toviyya says that Rav says; and some say Rav Ḥana bar Bizna says that Rabbi Shimon Ḥasida says; and some say Rabbi Yoḥanan says in the name of Rabbi Shimon ben Yoḥai: It is more comfortable for a person to cast himself into a fiery furnace, than to humiliate another in public to avoid being cast into the furnace.
