Negaim 8:6-7

Negaim 8:6

Let’s say that there are two white spots, one ritually unclean and the other ritually clean. If these broke out from one to the other and then they later broke out all over, the person is ritually clean. If the two spots were on his upper and lower lip, on two fingers or eyelids, then even though they join together and appear to be one spot, the person is ritually clean. If the tzaraas broke out all over except for a dull white spot, he is unclean. If the ends of his limbs reverted to the dull white color, he is clean. If the ends of his limbs revert to healthy flesh smaller than a lentil, Rabbi Meir rules him unclean. The Sages, however, rule that dull white (or healthy) flesh smaller than a lentil is a sign of impurity in the beginning but not at the end.

Negaim 8:7

One who came to a kohein completely white must be quarantined. If white hair grew, he is confirmed unclean. If both or one of the hairs turned black or became short, if a boil adjoined or encompassed both or one of them, or they were separated by a boil, the healthy flesh of a boil, a burn, the healthy flesh of a burn or a dull white spot (then the person in question is ritually clean). If healthy flesh or white hair appeared, he is unclean; if neither healthy flesh nor white hair appears, he is clean. In all these cases, if the ends of his limbs reverted to their pre-tzaraas condition, they are as they were before (i.e., ritually clean). If tzaraas later broke out over part of this person, he is unclean; if it broke out over all of him, he is clean.
