And if the priest looks, and, behold, the plague be somewhat dark after the washing of it; then he shall tear it out of the garment, or out of the skin, or out of the warp, or out of the woof:
And the priest shall look at the plague, after it is washed: and, behold, if the plague has not changed its color, and the plague be not spread; it is unclean; you shall burn it in the fire; it is going inward, whether it be bare within or without.
And if it appears still in the garment, either in the warp, or in the woof, or in anything of skin; it is a spreading plague: you shall burn that in which the plague is with fire.
