Leviticus 13:56

And if the priest should look, and the spot be dark after it has been washed, he shall tear it off from the garment, either from the warp or from the woof, or from the skin.

And if the priest look, and, behold, the plague be somewhat dark after the washing of it; then he shall rend it out of the garment, or out of the skin, or out of the warp, or out of the woof:

If the priest looks, and behold, the plague has faded after it is washed, then he shall tear it out of the garment, or out of the skin, or out of the warp, or out of the woof;
