כִּ֤י יְאַלֵּ֣ף עֲוֺנְךָ֣ פִ֑יךָ וְ֝תִבְחַ֗ר לְשׁ֣וֹן עֲרוּמִֽים׃
Sebab kesalahanmu mengajari mulutmu, padahal seharusnya engkau memilih tutur kata orang-orang yang arif.
Pesachim
At the academy of R. Ishmael, it was taught that a man should always speak in clean language, since the seat of a male zab the passage calls (Lev. 15:9) saddle, and the seat of a female zab the passage calls (Ib.) sitting place. This principle is also supported by the following passage (Job 15:6 ) So that thou choosest the language of the prudent. Also by another passage (Ib. 33, 3) And my lips utter knowledge clearly.
