2,934. A Nazir Who's a Doubtful Metzora

Hilchos Nezirus 9:19

The previous halacha (about a corpse on a path) applies when the nazir was walking. If he was riding or carrying a load, then he is ruled unclean. This is because it’s possible for a pedestrian not to touch, pass over or move a corpse, but such is not the case for one who is carrying a load or riding when a corpse is lying across his path.

Hilchos Nezirus 10:1

One can’t shave simultaneously for both nezrius and tzaraas (colloquially, “leprosy,” but not really). If a person is a doubtful metzora (“leper”), shaving for tzaraas doesn’t take priority over his nezirus. Let’s say that someone vowed nezirus for a year and during that year there was a doubt as to whether he contracted tzaraas and a doubt as to whether he was rendered unclean through corpse impurity, or if he was a doubtful metzora during the year and at the end of the year there was a doubt as to whether he was rendered unclean. In such a case, he counts seven days and has the purification water sprinkled on him on the third and seventh days, but he doesn’t shave on the seventh day. He may not drink wine or allow himself to be rendered unclean through corpse impurity for four years (because that’s how long it will take to complete all the shavings from his various cases of doubt). He may eat consecrated food after two years (because he will have had the two shavings required of a nazir). He’s obligated to shave four times – his shaving in purity, his shaving in impurity out of doubt, and the two shavings of a metzora out of doubt.
