Sotah 3A

אלמא קסברי דאסור לקנאות.

Apparently, both Reish Lakish and Rav Yeimar bar R' Shelemya hold that it is prohibited to issue a warning. Both are of the opinion that the word kinnui is a term for anger. Since causing anger is a negative trait, it follows that it is prohibited to issue a warning.

ומאן דאמר מותר לקנאות, מהו לשון ״קינוי״? אמר רב נחמן בר יצחק: אין ״קינוי״ אלא לשון התראה, וכן הוא אומר: ״ויקנא ה׳ לארצו״.

The Talmud asks: And according to the one who says that it is permitted for him to issue a warning, what is the meaning of the term kinnui? Rav Naḥman bar Yitzḥak says: The term kinnui means nothing other than a term of forewarning, and so it says: “Then YHWH warned [vayekanneh] concerning His land and had pity for His people” (Joel 2:18). As detailed in that passage, YHWH ordered the locusts to stop destroying Eretz Yisrael.

תניא, היה רבי מאיר אומר: אדם עובר עבירה בסתר והקדוש ברוך הוא מכריז עליו בגלוי, שנאמר: ״ועבר עליו רוח קנאה״, ואין עבירה אלא לשון הכרזה, שנאמר: ״ויצו משה ויעבירו קול במחנה״.

It is taught in a baraita that R' Meir would say: A person commits a transgression in private and God proclaims about him openly, i.e., in public, that he transgressed, as it is stated concerning a sota, who transgressed in private: “The spirit of jealousy came [avar] upon him” (Numbers 5:14); and the term avira means nothing other than a term of proclamation, as it is stated: “And Moses gave the commandment, and they caused it to be proclaimed [vaya’aviru] throughout the camp” (Exodus 36:6).

ריש לקיש אמר: אין אדם עובר עבירה אלא אם כן נכנס בו רוח שטות, שנאמר: ״איש איש כי תשטה אשתו״, ״תשטה״ כתיב.

Reish Lakish says: A man commits a transgression only if a spirit of folly [shetut] enters him, as it is stated: “If any man’s wife goes aside [tisteh]” (Numbers 5:12). The word tisteh is written with the Hebrew letter shin, affording an alternative reading of tishteh, which is related to the term for folly, the word shetut.
