A person was isolated for tzara'at and then the blemish spread to cover his entire body. What is the ruling?
Halacha 1 states that if a person who was isolated or declared definitively impure then has tzara'at spread over his entire body, he is declared pure.
Question 2
A person was released as pure from his two-week isolation (no signs appeared), then total whiteness covered his body. What is the ruling?
Halacha 1 clarifies this distinction: if total whiteness appears after release, the person is declared definitively impure (muchlat), not pure. Only whiteness appearing during isolation or during impurity purifies.
Question 3
After total whiteness purifies a person, what is the only sign that can make them impure again?
Halacha 3 explains from the verse 'On the day he exhibits healthy flesh, he will be deemed impure' — after total whiteness, only michyah (healthy flesh) can restore impurity. White hair alone does not re-impure such a person.
Question 4
A person's entire body turns white except for a lentil-sized patch at the tip of his finger. What is the ruling?
Halacha 4 states that even the tips of limbs that cannot cause michyah impurity when surrounded by a baheret do impair and prevent the purity of total whiteness — even a lentil at a finger tip maintains impurity.
Question 5
After total whiteness and then a cycle of michyah (impure) and re-coverage (pure) repeats 50 times — is this possible?
Halacha 5 explicitly states that this cycle of impurity (lentil of flesh) and purity (total re-coverage) may repeat even 100 times — there is no upper limit.
