Leviticus [Pertaining to Levites] 13:54-56

⁵⁴then the priest shall enjoin that they wash the thing in which the plague is, and he shall isolate it seven more days. (RY:4, LY:7)

⁵⁵Then the priest shall examine it, after the plague is washed; and behold, if the plague has not changed its color, and the plague has not spread, it is unclean; you shall burn it in the fire. It is a tzara'at mildewed spot, whether the bareness is inside or outside.

⁵⁶If 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 fabric, or out of the leather: (LY: Maftir ·Conclusion·)
