Another question that the rabbis take on involves shaving one's head. There is a Torah based negative prohibition against cutting the corners of one's hair. But there is a positive rabbinic commandment to shave one's entire head at the conclusion of one's nazirut. The rabbis suggest that the instruction to shave one's head after nazirut is from Sinai, and thus has the status of Torah law. As such, that commandment overrules the negative commandment to "not shave the corners" of one's head.
The daf also discuses the parallel issue of uncertain sacrifices, the offerings of zavot and zavim, when offerings are eaten and when they are burned, and the differences between women and men when it comes to uncertain sacrifices. Our notes sum up much of this discussion in listing of halachot:
- one who slaughters a bird in order to eat meat should use the 'pinching' method of slaughter
- uncertain bird offerings (for example, as brought by women who are unsure whether or not their miscarriages should be considered 'births' or an uncertain zava) are not eaten but burned like invalid offerings
- Definite sin: a man brings a sin-offering when he unwittingly transgresses a prohibition punishable by karet if it had been transgressed intentionally
- Definite sin: a woman after childbirth and a lava bring a pigeon or turtledove as a sin-offering
- Uncertain transgression: a man brings a provisional guilt-offering if he committed a sin where its accidental performance obliges him to bring a fixed sin-offering
- Uncertain transgression: a zava or a woman who is unsure whether or not her miscarriage should be considered a birth brings an offering due to uncertainty
- a man who is unsure whether he has accidentally committed a sin that, if performed intentionally, results in karet, must bring a provisional guilt-offering. This offering is eaten by priests in the Temple courtyard.
