Likutei Sichos – Vol 18 p 63 ff – Hadran on Meseches Nazir, Class One.
Siyum of Meseches Nazir; argument between Rav Nihorai and Rav Yosi, whether only Shimshon was a Nazir (from birth) or was Shmuel also a Nazir?
The Rebbe flushes out the nature of their argument (in the second class); here he explores the following questions:
1) Question of the partial גזירה שוא from Shimshon (who was not a complete Nazir) to Shmuel (who was a Nazir Olom).
2) Question of Nezirus vowed by one’s mother and the word of the Malach.
3) Answer: from the law of conversion of a child who later grows up, that he’s automatically Jewish unless he protests, and the same is true here.
The argument between Rav Nihorai and Rav Yosi is- how far does this argument goes.
