Leviticus 13:28-30 Catholic Public Domain Version (CPDV)

28. But if the whiteness stays in its place and is not very clear, it is the mark of a burn, and for this reason he shall be declared clean, because it is only the scar from a burn.

29. If leprosy will have sprung up in the head or the beard of a man or woman, the priest shall look upon them,

30. and if the place is certainly lower than the rest of the flesh, and the hair is golden, and thinner than usual, he shall declare them contaminated, because it is the leprosy of the head and the beard.
