יַרְשִֽׁיעֲךָ֣ פִ֣יךָ וְלֹא־אָ֑נִי וּ֝שְׂפָתֶ֗יךָ יַעֲנוּ־בָֽךְ׃
너를 정죄한 것은 내가 아니요 네 입이라 네 입술이 너를 쳐서 증거하느니라
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.
