מַה־נִּמְרְצ֥וּ אִמְרֵי־יֹ֑שֶׁר וּמַה־יּוֹכִ֖יחַ הוֹכֵ֣חַ מִכֶּֽם׃
옳은 말은 어찌 그리 유력한지, 그렇지만 너희의 책망은 무엇을 책망함이뇨
Rashi
How clear Heb. נמרצו, like (I Kings 2:8), “a clear curse (נמרצת),” an expression of (Prov. 25:11) “a word spoken with proper basis.” and similarly (Ps. 119:103), “How clear (נמלצו) are Your words to my palate.” All of them are expressions of clarification (מליצה), and the “lammed” is converted to a “resh.”
Rashi
words of uprightness If you were saying words of uprightness, they would be accepted, but now, what does your proof prove? Every expression of תוֹכָחָה in Job means the clarification and verification of matters.
