Zavim 2:1-2

Zavim 2:1

Everyone is rendered unclean by a zav emission, including converts, servants – whether or not they’ve been freed, a person with congenital deafness, a person lacking mental competence, a minor and a eunuch – whether he was castrated by a person or whether he was born that way. Regarding a hermaphrodite and a person of indeterminate gender, both the stringencies of a man and the stringencies of a woman apply to them: they are rendered unclean both through blood like a woman and through white like a man. Their cases of ritual impurity remain in doubt.

Zavim 2:2

A zav is examined in seven ways before being confirmed as a zav: regarding food, drink, what he had carried, if he jumped, if he had been ill, what he saw, and what he thought. (All of these things mitigate his impurity.) It makes no difference whether he had unclean thoughts without seeing a woman or whether he saw a woman without having unclean thoughts. Rabbi Yehuda says the same is true even if he saw domesticated or wild animals or birds copulating, or even if he saw a woman’s colorful clothes. Rabbi Akiva said even if he ate any kind of food, whether good or bad, or drank any kind of beverage. The Sages said to him that if such were the case, there wouldn’t be any zavim in the world! He answered them that it’s not their job to make sure there are zavim. Once a person becomes a zav, he is no longered examined. If an emission was caused by an accident, or if it’s in doubt, or if he has a seminal emission, these are unclean because there’s a basis (to assume they’re zav emissions). If a man had one emission, he’s examined; after a second, he’s examined. After a third, however, he isn’t examined. Rabbi Eliezer says he’s examined even after the third to determine if he needs to bring an offering.
