היה עומד בתפלה ויצא ממנו רוח מלמטה ממתין עד שיכלה הריח וחוזר ומתפלל:
There is a teaching : R. 'Akiba said : Once I went into a privy behind R. Joshua and learned from him three things. I learned that we should not "evacuate" East or West, but North or South. I learned that we should not expose ourselves standing but sitting. I also learned that we should not wipe ourselves with the right hand but with the left. Ben 'Azzai said to him, "Were you really so disrespectful with your master?" He replied, "It was a matter of Torah and I wished to learn."
Why should we not wipe with the right hand but only with the left? Raba said : Because the Torah was given with the right hand ; as it is said, "At His right hand was a fiery law unto them" (Deut. xxxiii. 2). Rabbah b. Bar Hannah said : Because it is near the mouths. R. Simeon b. Lakish said: Because he binds the Tefillin with it. Rab Nahman b. Isaac said: Because he points to the accents of the Torah with it.
