ציטירנדיקער פּירוש אויף שמות 33:8

The reason the word ישא is in the future tense instead of in the past tense, is because after the episode with the golden calf the Israelites were deprived of the crowns we have mentioned (Exodus 33,5), whereas Moses received them (Shabbat 88). This is based on a concept developed in Chagigah 15 that two places are reserved for each person, one in purgatory and one in Paradise. The one who forfeits his place in Paradise leaves it for his colleague who is more deserving, and the same is true for those who vacate their place in purgatory. This is the mystical dimension of Exodus 33,8 that "the people looked after Moses." Our sages in Sanhedrin 110 explain this to mean that each Israelite suspected Moses of committing adultery with his wife. This is not to be understood literally, of course, but it means that the Torah which was considered as betrothed to the Jewish people had become Moses' exclusive bride seeing he had taken over the parts that the people had previously been entitled to. By the Torah writing ישא in the future tense we receive the assurance that the removal of the crowns of the Israelites after the episode with the golden calf is reversible and that the time will come when they will once more merit and receive these crowns. Our sages (a glossary in the prayer-book edited by the Ari Zal) state that these crowns return to the heads of the Israelites on every Sabbath and that on the Sabbath Moses retains only his own crown. This is the reason that we say in the Sabbath morning prayer that Moses rejoices in his (personal) share, i.e. even though on that day he retains only this single crown.

The first announcement is, what is concluded in the Midrash Rabbati (Metzora 16:2): There was a story about one peddler who was going around towns near Tzippori and would announce and say, “Who wants to buy an elixir of life?” A crowd gathered around him. The author of Matnot Kehunah explains that they looked after him, similar to And they looked after Moses (Exodus 33:8). Rabbi Yannai was sitting and teaching in his reception hall. He said to the peddler, “Come up here and sell to me.” The peddler replied, “You don’t need it, nor do people like you.” Rabbi Yannai pressed him, so he went up to him. The peddler took out a wrapped book of Psalms and showed him this verse: Who is the man who desires life… Guard your tongue from evil (Psalms 34:13–14). Rabbi Yannai said, “Even Solomon announces: He who guards his mouth and his tongue, guards his soul from troubles (Proverbs 21:23) — guards his soul from leprosy.” Rabbi Yannai said, “All my days I had been reading this verse but did not know how its simple meaning was understood until this peddler came and informed me.” Therefore, Moses warns Israel: This shall be the law of the metzora [leper] — the one who brings forth evil [playing on the word metzora as motzi ra — one who speaks evil]. End of quote.

And about them Solomon said: Dead flies cause the ointment to stink etc. (Ecclesiastes 10:1). This means those with evil tongues who are compared to flies, and with the breath of His lips He kills, for evil speech kills three people (Devarim Rabbah 5:10). Therefore he called them dead flies and said cause to stink, because their entire intention is to make the reputation of good people stink. He sends forth a stinking savor of the ointment of the apothecary — sends forth is an expression of speech, meaning that even about a perfect person whose reputation is as fragrant as perfumed oil, nevertheless, he strives to make his reputation stink. A little folly is weightier than wisdom and honor — because in his eyes, that small folly that he sees in others is more precious and honorable to him than all the wisdom and honor he sees in them, until this small folly outweighs all the wisdom and honor.
And he gives a reason for this: A wise man’s heart is at his right hand (Ecclesiastes 10:2), meaning to judge people favorably, as our Sages said (Tanchuma, Shemot 18), “These are those who go to the right to find merit, etc.” But a fool’s heart is at his left — to judge people unfavorably. Therefore, he never speaks of others’ virtues, only their disgrace.
The reason for this is that even on the road where the fool walks, his heart is lacking, and he says to all that he is a fool (Ecclesiastes 10:3). This means that “whoever disqualifies others, with his own defect he disqualifies them” (Kiddushin 70b). This fool who suspects the innocent knows within himself that the same deficiency and flaw he attributes to others exists in himself, and his own heart is also lacking in that matter. Therefore, he says to all that they are fools, attributing to others the same foolishness that he knows exists primarily in himself, thinking that since he acts this way, everyone does the same.
These are the flies that constantly investigate people’s flaws and deficiencies, as it is said they looked after Moses (Exodus 33:8). Therefore, they were afflicted with leprosy, which is called “ra’atan” [a type of skin disease]. Just as they are possessors of “ra’atan” [from the root “to see”] who look at and observe the defects of people, so they were afflicted with leprosy called “ra’atan.” And they [the Sages] said to beware of them and not to deal with them to return them from their evil ways or to show them the way of repentance, because he thought that a slanderer has no remedy. Therefore, do not deal with them in vain. This was also the opinion of Rabbi Zeira, Rabbi Ami, and Rabbi Asi, who distanced themselves from their territory [of those who spoke evil speech] in all kinds of ways, as it concludes there.
