וְהִגַּ֣דְתִּי ל֔וֹ כִּֽי־שֹׁפֵ֥ט אֲנִ֛י אֶת־בֵּית֖וֹ עַד־עוֹלָ֑ם בַּעֲוֺ֣ן אֲשֶׁר־יָדַ֗ע כִּֽי־מְקַֽלְלִ֤ים לָהֶם֙ בָּנָ֔יו וְלֹ֥א כִהָ֖ה בָּֽם׃
내가 그 집을 영영토록 심판하겠다고 그에게 이른 것은 그의 아는 죄악을 인함이니 이는 그가 자기 아들들이 저주를 자청하되 금하지 아니하였음이니라
Rashi
That his sons were blaspheming themselves. It should properly state, 'blaspheming Me' but Scripture euphemized.12 See Mechilta Beshalach 15:7 for a listing of other places where Scripture euphemized out of reverence to ‘ה. Ralbag, however, interprets this verse that “they [Bnei Yisroel] cursed them [the sons of Eili].”
Rashi
Blaspheming. Meaning, acting irreverantly, and similarly, every curse [קְלָלָה] is an expression of irreverence and disgrace.
Rashi
He did not censure. I.e., he did not darken [כהה] their faces by removing them from their high positions.
