The Halacha follows רב הונא that if the כתם is a גריס size it did not come from a louse.
- True, because Rav Huna was Rav Chisda's Rebbe.
- False, since Rashi writes that the Halacha follows רב חסדא who is lenient.
- Machlokes A&B.
- איבעיא דלא איפשטא.
- כתמים are דאורייתא so we have to be מחמיר.
Is it ever possible to be lenient if we find more than a גריס?
- Everyone agrees that חז"ל fixed that the maximum is כגריס.
- If a louse was squashed into the כתם Rav Yanai is מטהר.
- If she was occupied with blood some are מיקל even for more than a כגריס.
- We are מיקל up to 2 גריסין.
- Both B&C are true.
R. Eliezer bar Tzadok - a streak of blood found on an עד placed under the pillow is טמא.
- Rabanan agree with R. Eliezer.
- We do not pasken like R. Eliezer.
- If the blood was in a round shape she is also טמאה.
- Rav Yehuda said the Halacha follows R. Eliezer which implies that Rabanan disagree with R. Eliezer.
- R. Eliezer said that even a streak of כתם is מטמא less than כגריס.
A woman urinated and saw blood
- According to R. Yosi if she was standing she is טמאה but if sitting she is טהורה
- According to R. Meir she is טהורה whether standing or sitting.
- R. Meir says she is טמאה if standing but טהורה if sitting.
- R. Yosi says she is טהורה whether standing or sitting.
- Both C&D are true.
What does R. Meir say if there are 2 doubts?
- Resh Lakish holds that R. Meir is מטמא even a ספק ספקא.
- R. Yochanan holds that R. Meir is מטהר a ספק ספקא.
- Both B&C are true.
- All agree that R. Meir permits a ספק ספקא.
- One cannot say that R. Yosi allows 1 ספק and R. Meir prohibits 2.
A טהורה Jewish lady borrowed a garment from a טהורה friend. Then the friend wore it and a כתם was found.
- They are both טמאות.
- They are both טהורות because כתמים are דרבנן.
- The friend is טמאה because she was the last one to wear it.
- The first lady is טמאה because the second lady had חזקת טהרה.
- בעיא דלא איפשטא.
