Leviticus 13:54-56

⁵⁴Then the Priest shall commaund them to wash the thing wherein the plague is, and he shall shut it vp seuen dayes more.

⁵⁵Againe ye Priest shall looke on the plague, after it is washed: and if the plague haue not changed his colour, though the plague haue spred no further, it is vncleane: thou shalt burne it in the fire, for it is a fret inwarde, whether the spot bee in the bare place of the whole, or in part thereof.

⁵⁶And if the Priest see that the plague bee darker, after that it is washed, he shall cut it out of the garment, or out of the skin, or out of the warpe, or out of the woofe.
