2,903. Resuming Nezirus
Hilchos Nezirus 6:12
The newly-purified nazir starts counting again when he brings his sin offering. Failure to bring his burnt offering and guilt offering do not prevent him from resuming his count.
Hilchos Nezirus 6:13
If he was sprinkled on the third and seventh days but did not immerse, delaying his immersion for some reason, then when he immerses he waits until sunset and brings his offerings on the next day. If he immersed himself and waited until sunset but delayed his offerings, he can’t resume counting until he brings his sin offering. As mentioned, delaying his burnt offering and guilt offering don’t prevent him from counting.
