If a nega broke out completely upon one who was unclean, he becomes clean; If the ends of his limbs reappeared, he becomes unclean until the bright spot is reduced to less than the size of a split bean. [If it broke out completely upon him] when he was clean, he becomes unclean; If the ends of his limbs reappeared, he remains unclean until his bright spot resumes its former size.

A bright spot the size of a split bean in which there was quick flesh the size of a lentil and then it broke out covering a person's entire skin and then the quick flesh disappeared, or if the quick flesh disappeared and then the bright spot broke out covering all his skin, he is clean. If quick flesh arose [subsequently], he is unclean. If white hair grew [subsequently]: Rabbi Joshua rules that he is unclean, But the sages rule that he is clean.

A bright spot in which there was white hair and then it broke out covering his entire skin, even though the white hair remained in its place, he is clean. A bright spot in which there was a spreading and then it broke out covering his entire skin, he is clean. But in all of these cases if [even] the ends of the his limbs reappeared [in their natural color], he is unclean. If it broke out covering a part of his skin he is unclean; If it broke out covering all his skin he is clean.

In all cases of breaking out and covering the ends of the limbs whereby the unclean have been pronounced clean, if they reappeared they become unclean again. In all cases of reappearance of the ends of the limbs whereby the clean have been pronounced unclean, if they were covered again these become clean again. If subsequently they become uncovered these are unclean, even if this occurs a hundred times.

Any part [of the body] that can be subject to the uncleanness of a bright spot nega can prevent the effectiveness of the breaking out [over the entire body], and any part that cannot be subject to the uncleanness of a bright spot nega does not prevent the effectiveness of the breaking out abroad. How so? If it broke out covering all of his skin, but not on the head or the beard, or on a festering boil, burn or blister, and then the head or the beard became bald, or the boil, burn or blister turned into a scar, he is clean. If it broke out covering all of his skin, except a spot of the size of half a lentil near the head or beard, or near a boil, burn or blister, and then the head or the beard became bald, or the boil, burn or blister turned into a scar, even though the place of the quick flesh became a bright spot, he is unclean unless it breaks out covering all his body.

If there were two bright spots, one unclean and the other clean, and they broke out from one to the other, and then [a nega] broke out covering all of his skin, he is clean. [If the bright spots] were on his upper lip and lower lip, or on two of his fingers, or on his two eyelids, even though they cleave together and appear as one, he is clean. If it broke out covering all his skin except white scurf, he is unclean. If the ends of his limbs reappeared in the color of white scurf, he is clean. If the ends of his limbs reappeared to the extent of less than a lentil: Rabbi Meir rules that he is unclean, But the sages rule that a piece of white scurf less in size than a lentil, is a sign of uncleanness in the beginning, but it is not a sign of uncleanness at the end.

One who came [in front of the priest] with all his body white is isolated. If white hair grew, he is certified unclean. If both hairs or one of them turned black, If both or one of them became short, If a boil adjoined both or one of them, If a boil surrounded both or one of them, Or if a boil, the quick flesh of a boil, a burn, the quick flesh of a burn, or white scurf divided them [he is pure]. If quick flesh or white hair arose, he is unclean; But if neither quick flesh nor white hair arose he is clean. In all these cases if the ends of his limbs reappeared he remains as he was before. If the nega broke out, covering a part of him, he is unclean. If it broke out covering all of them, he is clean.

If it broke out covering all of his skin all at once: If this originated in a condition of cleanness, he is unclean; But if it originated in a condition of uncleanness, he is clean. One who becomes clean after having been isolated is exempt from the uncovering his head and rending his clothes, from shaving his hair and from bringing the birds. If he becomes clean after he had been certified unclean, he is liable to all these. Both convey uncleanness by entering.

If one came with his whole body white, and on it there was quick flesh to the extent of a lentil, and then the nega spread out covering all his skin, and then the ends of his limbs reappeared: Rabbi Ishmael says: this is the same as when the ends of the limbs reappear in that of a large bright spot. Rabbi Elazar ben Azariah ruled: as when the ends of the limbs reappeared in a small bright spot.

There is one who shows his nega [to the priest] and thereby gains advantage, while there is one who shows and loses. How so? If one was certified unclean and the signs of his uncleanness disappeared, and before he could show it to the priest the nega broke out covering all his skin, he is clean; whereas if he had shown it to the priest he would have been unclean. If he had a bright spot in which there was nothing else, and before he could show it to the priest it broke out covering all his skin, he is unclean; whereas if he had shown it to the priest he would have been clean.
