2,939. A Nazir Who's Sure That He’s a Metzora But Unsure If He’s Unclean (and Vice Versa)

Hilchos Nezirus 10:10

If a nazir is sure that he’s a metzora and unsure if he’s ritually unclean, then after his purification from tzaraas he has the purification waters sprinkled on him on the third and seventh days. He shaves for ritual impurity and starts observing the days of his nezirus in full. This is because the days he already observed are voided by his doubtful ritually uncleanliness. He brings his purity offerings, after which he can drink wine. He can eat sacrificial foods after he brings his tzaraas offerings.

Hilchos Nezirus 10:11

If the nazir is sure that he's ritually unclean but unsure if he's a metzora, then after being purified from tzaraas he observes the days of his nezirus in full, after which he shaves (for the tzaraas). This is because a shaving out of doubt doesn’t override nezirus. He then counts the seven days between a metzora’s first and second shavings and he shaves again. He brings his offerings, after which he can eat sacrificial foods so long as he had the purification waters sprinkled on him on the third and seventh days. He then counts another seven days for the corpse uncleanliness and shaves for ritual impurity. Finally, he observes his nezirus in full.
