Leviticus 13:27-37

²⁷And the priest is to see him again on the seventh day; if it is increased in the skin, then the priest will say that he is unclean: it is the leper's disease.

²⁸And if the bright place keeps the same size and gets no greater on the skin, but is less bright, it is the effect of the burn, and the priest will say that he is clean: it is the mark of the burn.

²⁹And when a man or a woman has a disease on the head, or in the hair of the chin,

³⁰Then the priest is to see the diseased place: and if it seems to go deeper than the skin, and if there is thin yellow hair in it, then the priest will say that he is unclean: he has the mark of the leper's disease on his head or in the hair of his chin.

³¹And after looking at the diseased place, if it does not seem to go deeper than the skin, and there is no black hair in it, then the priest will have him shut up for seven days:

³²And on the seventh day the priest will see the place: and if it is not increased, and there is no yellow hair in it, and it does not seem to go deeper than the skin,

³³Then his hair is to be cut off, but not on the diseased place, and he is to be shut up for seven days more:

³⁴And on the seventh day the priest will see the place: and if it is not increased, and does not seem to go deeper than the skin, the priest will say that he is clean: and after his clothing has been washed he will be clean.

³⁵But if the disease in his skin becomes worse after he has been made clean,

³⁶Then the priest is to see him: and if the mark is increased, the priest, without looking for the yellow hair, will say that he is unclean.

³⁷But if, in his opinion, the growth is stopped, and black hair has come up on it, the disease has gone; he is clean and the priest will say that he is clean.
