A person has three white hairs in his baheret and pulls out one before the priest arrives. Is he liable for lashes?
Halacha 1 states that although removing signs violates a prohibition, one is only liable for lashes if the action is effective. With three hairs, removing one leaves two — still impure — so no lashes, though he receives stripes for rebellious conduct.
Question 2
A person removes his white hairs during his isolation period (before declaration of impurity). After the isolation ends, what is his status?
Halacha 2 states: if signs are removed before coming to the priest or during the isolation period, the person is considered pure after the isolation ends. Removal is only futile if done after definitive ruling of impurity.
Question 3
What activities is a declared metzora FORBIDDEN from doing?
Halacha 6 states the metzora is forbidden from cutting hair, laundering clothes, and greeting others. He may, however, bathe, anoint himself, wear sandals, and engage in marital relations.
Question 4
A metzora enters a building. What happens to the people and items inside?
Halacha 11 explains: when a metzora enters a building, everything in it (humans and implements) contracts impurity even without contact. This is derived from 'outside the camp shall be his dwelling' — just as he is impure, his dwelling-place is impure.
Question 5
In which cities must a declared metzora live outside the town walls?
Halacha 7 states the law of living outside the camp applies only to walled cities in Eretz Yisrael — derived from 'outside the camp shall be his dwelling' (Leviticus 13:46).
