A high priest and a nazirite may not defile themselves with their [dead] relatives, but they may defile themselves with a neglected corpse. If they were walking on the path and found a neglected corpse: Rabbi Eliezer says: the high priest should defile himself but not the nazirite. But the Sages say: the nazirite should defile himself but not the high priest. Rabbi Eliezer said to them: the priest should defile himself, for he does not offer a sacrifice for his defilement, and the nazirite should not defile himself, for he does offer a sacrifice on defilement. They said to him: the nazirite should defile himself, for his holiness is not permanent, and the priest should not defile himself, for his holiness is permanent.

For which types of defilement must the nazirite shave?For [defilement contracted from] a corpse, or an olive’s bulk of [the flesh of] a corpse, or an olive’s bulk of corpse ooze, or a ladleful of corpse-mould; Or the spinal column, or the skull, or any limb [severed] from a corpse, or any limb [severed] from a living body that is still properly covered with flesh, or a half-kav of bones, or a half-log of blood. Whether [the defilement was contracted] from contact with them, from carrying them, or from overshadowing them. For [defilement contracted from] a barley-grain’s bulk of bone, whether by contact or carrying. On account of these, a nazirite must shave and be sprinkled on the third and seventh days, and such [defilement] annuls the previously served period, and he does not begin to count a new [naziriteship] until he has become clean and brought his sacrifices.

Rabbi Eliezer said in the name of Rabbi Joshua: for every defilement [conveyed] by a corpse on account of which a nazirite must shave, people are liable for entering the sanctuary, and for every defilement [conveyed] by a corpse on account of which a nazirite does not shave, people are not liable for one entering the sanctuary. Rabbi Meir said: such [defilement] should not be less serious than [defilement through] a dead creeping thing. Rabbi Akiba said: I argued in the presence of Rabbi Eliezer: Now if on account of a barley-corn’s bulk of bone which does not defile a man by overshadowing, a nazirite shaves should he touch it or carry it, then surely a quarter-log of blood which defiles a man by overshadowing, should cause a nazirite to shave should he touch it or carry it? He replied: What is this Akiva! We do not make here an ‘all the more so’ (a kal vehomer) argument. When I afterwards went and recounted these words to Rabbi Joshua, he said to me, “You spoke well, but thus they have ruled the halakhah.”
