Leviticus 13:45
And the leper in whom the plague is, his clothes shall be rent, and his head bare, and he shall put a covering upon his upper lip, and shall cry, Unclean, unclean.
Leviticus 13:55
And the priest shall look on the plague, after that it is washed: and, behold, if the plague have not changed his color, and the plague be not spread; it is unclean; thou shalt burn it in the fire; it is fret inward, whether it be bare within or without.
