יֵ֣שׁ בּ֭וֹטֶה כְּמַדְקְר֣וֹת חָ֑רֶב וּלְשׁ֖וֹן חֲכָמִ֣ים מַרְפֵּֽא׃
Il en est dont la parole blesse comme des coups d’épée, mais, le langage des sages est un baume bienfaisant.
Rashi
There is one who speaks Heb. בוטה, speaks, as in (Lev. 5:4): “to pronounce (לבטה) with the lips.”
Rashi
like the jabs of a sword For he stirs up the people and causes them to kill.
Rashi
but the tongue of the wise which brings peace between one man and his fellow.
