Mishnayos Nazir Perek 6 Mishnah 6

With regard to the shaving of ritual impurity performed by a nazirite who became impure during his naziriteship, how is it performed? The priest would sprinkle the waters of purification on him on the third and the seventh days after he contracted his impurity, as performed for all those who contracted impurity imparted by a corpse. And he shaves his hair on the seventh day and brings his offerings on the eighth day. And if he shaved on the eighth day he brings his offerings on that day, this is the statement of Rabbi Akiva. Rabbi Tarfon said to him: What is the difference between this ritual and that of a leper? A leper also shaves on the seventh day and sacrifices his offerings on the eighth. However, if a leper shaves on the eighth day he brings his offerings on the ninth day, not on the day of his shaving. Rabbi Akiva said to him: The purification of this impure nazirite depends on his days, as he immerses on the seventh day like all those who contract impurity imparted by a corpse, which means he is already ritually pure on the eighth day. But with regard to a leper, his purification depends on his shaving. Any immersion performed earlier is of no account, and must be repeated. And a leper brings his offering only if the sun has set following his immersion. Since offerings are not sacrificed at night, the bringing of his offering is postponed until the following day.
