The purification of a person afflicted with tzara'at is a positive commandment and his shaving is also a positive commandment. How is a person who had been afflicted by tzara'at purified? He should bring a new earthenware container - the Received Tradition teaches that it must be new. A fourth of a log of "living water" that is fit to be sanctified as water for the sprinkling of the ashes of the red heifer is placed in it. This measure is a Rabbinic institution. Two sparrows that are kosher must be brought for the sake of purifying a tzara'at affliction, as Leviticus 14:4 states: "For the one who is to be purified will be taken...." He should slaughter the healthier of the two over the water in the earthenware vessel and squeeze out the blood until it is apparent over the water. He then digs a hole and buries the slaughtered bird in the presence of the afflicted person. This is one of the points received through the Oral Tradition. He takes a cedar branch - the mitzvah is that it be a cubit long and a fourth the thickness of a bedpost. And he takes a hyssop whose name is not described by an additional term, as we explained, that is not less than a handbreadth long, and a crimson strand weighing a shekel. If one used the dye for another purpose, it is disqualified, as is the rule regarding dyeing wool with blue dye to use for tzitzit. All of these measures are laws transmitted to Moses at Sinai. A priest takes the three items mentioned above together with the living fowl. All these four items are fundamental requirements. When the cedar branch and the hyssop have been peeled, they are invalid. The hyssop should be bound together with the cedar branch with the crimson thread. The tips of the wings and the tips of the tail of the living bird should be held close to them and the four should be dipped in the water in the container and the blood floating on top of it. He then sprinkles with them seven times on the back of the hand of the afflicted person and sends away the fowl. How does he send the fowl away? He stands in the town and casts it outside the wall. He does not turn its head to the sea, to the town, or to the desert, as ibid.:53 states: "Outside the city, towards the field." If he sends away and it returns, he should send it away again, even 100 times. Afterwards, the priest shaves the afflicted person. How does he shave him? He passes a razor over all his skin that is visible including his underarms and pubic region until his entire flesh is smooth like a squash, as ibid.:9 states: "He shall shave all of his hair." If so, why does the verse mention his beard and his eye-brows? To include everything like them and to exclude the hair in the nose, because it is not visible. Afterwards, he "launders" his garments, immerses himself, and becomes pure with regard to conveying impurity when he enters a building or to the article on which he lies or sits. He may enter within the town's wall. He counts seven days. During them, he is forbidden to engage in physical intimacy, as alluded to by ibid.:8: "outside his tent." This teaches that he is forbidden physical intimacy. A woman afflicted by tzara'at, by contrast, is permitted physical intimacy.
