If a nazirite cuts his hair in the middle of his vow, how many sets of lashes does he receive?
He receives two sets of lashes: one for the specific nazirite prohibition (no razor) and one for the general prohibition against desecrating one's vow (Halachah 2).
Question 2
A person sees a nazirite walk past and says 'I will be' — is he a nazirite?
Since he had the intention in his heart and expressed it through words that suggest nazirism (yadot nedarim), he is a nazirite even without explicit language (Halachah 6).
Question 3
If someone says 'I am a nazirite from grape seeds only,' what is his status?
Since grape seeds are forbidden to nazirites, declaring oneself a nazirite from that item triggers full nazirite status (Halachah 9).
Question 4
A grieving man given wine says 'I am a nazirite from this cup' to avoid drinking it. What is his status?
His intent was only to refuse that particular cup, not to undertake a nazirite vow, so he is forbidden only from that cup (Halachah 11).
Question 5
A man vows 'I will be a nazirite when offspring is born to me' and his wife gives birth to a daughter. Is he a nazirite?
The word 'offspring' (walad) includes all children regardless of gender. Only if he said 'son' (ben) would a daughter not trigger the vow (Halachah 18).
