mentions that zav status can also mean complete loss of ejaculation ability. Maimonides understands the same word as meaning even a minute amount of ‘Zav’ discharge that passes the exiting boundary of the male urinary tract. Laws If a man observes the abnormal discharge once, he becomes impure for a single day, like one who ejaculated normal semen. If he observes the discharge twice, the full seven-day period of impurity is required. If he observes it three times, he is also required to bring the specified sacrifice. These observations can occur on the same day, or on consecutive days. Only after the week's wait and immersion would he become ritually pure once more (), but he would not be permitted to eat terumah until nightfall nor to eat the flesh of a sacrifice until after bringing his sacrifice. The zav is quantified as an Av HaTumah, something able to transfer uncleanliness. In addition, his actual zav discharge, saliva, semen, and urine are also deemed to have Av HaTumah status. In regard to the transportability of tumah from the zav, the Mishnah records that if a ritually clean person and a zav both sat on an animal, or in a small boat, then the ritually clean person would become ritually unclean by doing so, regardless of how far apart they might sit. This is known as hesset ("minor movement"). Regular ejaculation is treated as being distinct from zav, and is known as keri (). Viewed as Divine punishment Ibn Ezra notes that the Torah requirement of bringing a sin-offering upon the completion of seven clean days is an indication that the zav committed a sinful act that incurred his zav status. Similarly, Hezekiah ben Manoah writes that the textual order of the zav laws near those of tzaraath and embezzlement (me'ilah), and demonstrate that zav status is incurred by lack of earnestness (to God) and sin. Rabbi Shabbatai HaKohen ("the Shach") comments that zav status is a divine consequence for excessive indulgence in physical relations that take place in the laying position. Thus, as consequence, items the zav will lay upon (i.e. midras objects) will become tamei (impure) for the duration of his zav state. In modern Judaism The laws of zav have little relevance nowadays, as a state of purity is only required for activities such as entering the Temple and eating terumah - activities which are not practiced nowadays.
