Nazir

Now to what use does the [Tanna] who utilizes [the phrase] 'his head' for the nazirite [leper], put [the phrase] 'his beard'?  — He requires it for [the following] that has been taught:  [From the verse] Neither shall they shave off the corners of their beard,  it might be thought that even if he shaved it with a scissors, he would be guilty, and so Scripture says [elsewhere], neither shalt thou mar [the corners of thy beard].  If it had [only written] 'neither shalt thou mar' It might have been thought that if he plucked it out with tweezers or a rohitni,  he would be guilty, and so Scripture says, 'neither shalt they shave off the corners of their beard'. What sort of shaving also mars? I should say that this is [shaving with] a razor. Now according to the other tanna who utilizes the phrase, 'his head' for [overriding] a simple prohibition, why is it necessary to write both 'his head' and 'his beard'? [For since the expression 'his head'] can be understood as implying the overriding of a simple prohibition  and it can be understood also as implying the overriding of a prohibition accompanied by a positive command,  it can be applied indifferently to both,  and both could be inferred?  — The priest [leper] cannot be inferred from the nazirite [leper], since the latter can secure release [from his nazirite vow].  The nazirite [leper] cannot be inferred from the priest [leper], since the [latter] prohibition does not apply equally to all people.  [Finally,] we cannot infer from these a rule for other cases,  since the previously mentioned objections could be raised. Rab said: A man may thin [the hair of] his whole body with a razor. An objection was raised. [It has been taught:] One who removes [the hair of] the armpits or the private parts is to be scourged?  — This [refers to removal] by a razor whereas the other of [Rab refers to removal] by a scissors. But Rab also mentions a razor? — [He means closely] as though with a razor. R. Hiyya b. Abba, citing R. Johanan said: One who removes [the hair of] the armpits or of the private parts is to be scourged. An objection was raised. [It has been taught:] Removal of hair is not [forbidden] by the Torah, but only by the Soferim?  — What he too meant by scourging is [scourging inflicted] by the Rabbis.
