Nazir 28B

תנא דידן סבר: כיון דאיזדריק עלה דם, לאלתר שריא בחמרא, והא לית לה ניוול. ורבי עקיבא סבר: אפילו אישתחיטת בהמה ⁠— אינו יכול להפר, משום הפסד קדשים.

The tanna of our Mishnah holds: Once the blood has been sprinkled on her behalf she is immediately permitted to drink wine, and therefore she is not downcast. Consequently, the husband has no right to nullify her naziriteship vow at that point, as her vow does not affect him. And R' Akiva holds: Even if the blood has yet to be sprinkled and wine remains forbidden to her, as soon as an animal is slaughtered for one of her offerings the husband can no longer nullify the vow, due to the loss of consecrated property. If he were to nullify her vow she would have no further need of the offerings, and it is prohibited to waste Sanctuary property.

מתקיף לה רבי זירא: ואמאי? לזרוק דמן שלא לשמן, ויתיר בשר באכילה! מי לא תניא: כבשי עצרת ששחטן שלא לשמן, או ששחטן לפני זמנן או לאחר זמנן ⁠— הדם יזרק והבשר יאכל.

R' Zeira objects to this: And why should the result be a loss to the Sanctuary? He can avoid this by sprinkling their blood not for the sake of the offerings of a nazirite, and he will thereby permit the meat of the offering to be eaten, and the consecrated animal will not go to waste. Isn’t it taught in a baraita: With regard to the communal peace-offering of two sheep that accompanies the two loaves on Shavuot, if one slaughtered them not for the sake of that offering, or slaughtered them before their time, on the eve of the Festival, or after their time, after the Festival, the blood should be sprinkled, although not for the sake of that offering, as it is no longer fit for that purpose, and the meat is eaten.
