In Jewish ritual law, a zav (Hebrew: זב; lit. "one who[se body] flows") 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.^[1]
