Leviticus 13:29-33 ▼

29 If a man or woman has a disease on the head or the beard;

30 Then the priest shall see the disease; and, if it appears deeper than the skin, and there be in it yellow thin hair, then the priest shall pronounce him unclean; because it is the disease of leprosy of the head or beard.

31 And if the priest look on the disease, and it does not appear deeper than the skin and there is no black hair in it; then the priest shall observe it seven days;

32 And on the seventh day the priest shall look on the disease; and if the disease has not spread, and if there is no yellow hair in it and the appearance of the disease is not deeper than the skin.

33 Then he shall shave the sides of the sore, but the sore he shall not shave; and the priest shall observe the disease seven days more;
