יֵ֣שׁ בּ֭וֹטֶה כְּמַדְקְר֣וֹת חָ֑רֶב וּלְשׁ֖וֹן חֲכָמִ֣ים מַרְפֵּֽא׃
Há palrador cujas palavras ferem como espada; porém a língua dos sábios traz saúde.

like the jabs of a sword For he stirs up the people and causes them to kill.

but the tongue of the wise which brings peace between one man and his fellow.
