Nazir

And again, suppose it is decided that [the naziriteship] [in this case] operates [immediately], what would be the law if he were to say 'I wish to be a nazirite after twenty days time' and then 'I wish to be a life nazirite now',  would this become operative [at once] or not?  And again, supposing it is decided that in all these cases, since it is possible to secure release,  they become operative [at once],  what would be the law if he were to say 'I wish to become a nazirite like Samson in twenty days time', and then 'I wish to be an ordinary nazirite now'? In this case, since release cannot be secured,  would it become operative or not? If he were to say, 'I desire to be as Moses on the seventh of Adar,'  what [would his meaning be]? Of these [questions], decide the first, [For it was taught: Should a man say] 'I wish to be a nazirite after twenty days time,' and then 'For a hundred days from now,' he reckons twenty days, and then thirty days, and then eighty days to complete the first naziriteship. [SHOULD HE SAY, 'I WISH TO BE A NAZIRITE WHEN I SHALL HAVE A SON, AND A NAZIRITE ON MY OWN ACCOUNT etc.'] If he contracts ritual defilement  during the period [of naziriteship] on account of his son, R. Johanan said: This renders void [the first  period as well], but Resh Lakish said: It is not void. 'R. Johanan said that it becomes void,' — because [the whole] is one long period of naziriteship; 'but Resh Lakish said that it is not void,' — since his own naziriteship, and the one on account of his son are distinct.
