Nazir 6:10-11

Nazir 6:10

If the nazir shaved after his sacrifice was offered but then the sacrifice was found to be invalid, his shaving is also invalid and none of his other sacrifices count. If he shaved after his sin offering was offered but it turned out that the sacrifice was not offered for the designated purpose, and then he brought his other sacrifices for their designated purposes, his shaving is invalid and his other sacrifices don’t count. Rabbi Shimon says that sacrifices not offered for their designated purposes don’t count but those offered for their designated purposes do count. If the nazir shaved after all three sacrifices were offered and one of them was found to be invalid, his shaving is valid and he can bring replacement sacrifices.

Nazir 6:11

If a nazir got splattered by blood from one of his sacrifices, rendering him unclean, Rabbi Eliezer says he loses all the sacrifices, while the Sages say that he can bring the rest of his sacrifices after he is purified. The Sages said to Rabbi Eliezer that Miriam of Tarmod was a nazir. The blood of one of her sacrifices was sprinkled when she received word that her daughter was dangerously ill. Miriam ran to see her but when she got there, her daughter was already dead (rendering Miriam unclean). The Sages permitted her to bring the rest of her sacrifices after being purified.
