Leviticus 13:35-36

³⁵Else if after the cleansing, a spot waxeth again in the skin, (But if, after they be pronounced clean, a spot groweth again, or spreadeth, in the skin,)

³⁶the priest shall no more inquire, whether the hair is changed into white colour, for apertly he is unclean. (the priest shall inquire no more, whether the hair is changed to white colour, or not, for they be openly unclean.)
