and the priest shall examine the diseased thing after it has been washed. And if the diseased spot has not changed color, though the disease has not spread, it is unclean; you shall burn it in the fire, whether the leprous spot is on the back or on the front.
then if it appears again in the garment, in warp or woof, or in anything of skin, it is spreading; you shall burn with fire that in which is the disease.
