Negaim 8:8-9

Negaim 8:8

If tzaraas broke out all over all at once, then if it started from a state of purity, he is ritually unclean; if it started from a state of impurity, he is ritually clean. One who becomes clean after being quarantined is exempt from the letting his hair grow, tearing his clothes, shaving his hair and bringing the bird offering. If he becomes clean after being confirmed unclean, then he is obligated in all these things. Both a confirmed and a quarantined metzora convey impurity to a house by entering it.

Negaim 8:9

Let’s say that one came to a kohein with his whole body white but there was a patch of healthy flesh the size of a lentil. If the tzaraas then spread all over, after which the ends of his limbs reverted to their pre-tzaraas appearance, Rabbi Yishmael says that it’s the same as when the ends of the limbs revert in one who had a large white spot. Rabbi Elazar ben Azariah says that it’s like when the ends of the limbs revert in one who had a small white spot.
