יֵ֣שׁ בּ֭וֹטֶה כְּמַדְקְר֣וֹת חָ֑רֶב וּלְשׁ֖וֹן חֲכָמִ֣ים מַרְפֵּֽא׃
혹은 칼로 찌름 같이 함부로 말하거니와 지혜로운 자의 혀는 양약 같으니라
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.
