The opening as it read in 2025
State of ritual impurity arising from abnormal seminal discharge from the male sexual organ For other uses, see Zav (disambiguation) . In Jewish ritual law, a zav ( Hebrew : זָב ; lit. "flowing") is a man who has had abnormal seminal discharge from the male sexual organ, and thus entered a state of ritual impurity . A woman who has had similar abnormal discharge from her genitals is known as a zavah . Purification requirements for the zav include counting seven days without seminal discharge, immersion in a spring , and bringing certain korbanot (sacrifices). In the realm of tumah and taharah law, the zav can create a midras and is prohibited from entering specific areas of the Temple Mount . The impurity of zav is unique in that it cannot be purified by immersion in a normal mikveh , but rather requires immersion in a spring of Living Water .

The opening as it stood in 2010
Zav and Zavah are states of ritual impurity in Judaism arising from certain bodily discharges; for men the state is termed zav , and for women it is termed zavah . The Jewish regulations and existence of these states have a biblical basis , and further specification of these rules exists in the Jewish Oral Law ; Orthodox Judaism views the Shulchan Aruch as being particularly authoritative on these matters, and it has extensive discussion about the subject. Normal menstruation is explicitly excluded from the biblical regulations concerning zavah , and is treated with separate requirements known as niddah ; the ejaculation of semen is also treated as being distinct from zav, and is given requirements known as keri . Therefore, in Jewish Law, most instances of zav or zavah stem from either urinating , defecating or vomiting .
