וְכָל־הַנֹּגֵ֔עַ בְּכָל־כְּלִ֖י אֲשֶׁר־תֵּשֵׁ֣ב עָלָ֑יו יְכַבֵּ֧ס בְּגָדָ֛יו וְרָחַ֥ץ בַּמַּ֖יִם וְטָמֵ֥א עַד־הָעָֽרֶב׃
A ktoby się téż dotknął jakiegokolwiek sprzętu, na którymby siedziała, wypierze szaty swoje i umyje się wodą, a nieczystym będzie aż do wieczora.
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.
