כִּ֤י יְאַלֵּ֣ף עֲוֺנְךָ֣ פִ֑יךָ וְ֝תִבְחַ֗ר לְשׁ֣וֹן עֲרוּמִֽים׃
Sebab kesalahanmu mengajari mulutmu, padahal seharusnya engkau memilih tutur kata orang-orang yang arif.
Rashi
For your iniquity teaches Your evil inclination [teaches] your mouth to speak such words, but you should have chosen the tongue of the crafty.
