Еврейская мысль к Мишлей 9:7

יֹ֤סֵ֨ר ׀ לֵ֗ץ לֹקֵ֣חַֽ ל֣וֹ קָל֑וֹן וּמוֹכִ֖יחַ לְרָשָׁ֣ע מוּמֽוֹ׃

Тот, кто исправляет пренебрежительного, становится позором для себя, а тот, кто обличает нечестивого, становится для него пятном.

Duties of the Heart

Miserliness is in place towards the cruel and foolish and those who do not recognize themselves, nor the value of the beneficence bestowed on them, as it is said, "He that reproves a scorner gets to himself shame: and he that rebukes a wicked man, it is a blemish to himself" (Prov. 9:7). Our wise men say, "He who does a favor to an ingrate is like a man who casts a stone to Markolis" (A form of idol worship in ancient times).
