Leviticus 13:54-56

New Revised Standard Version, Anglicised Catholic Edition

⁵⁴ the priest shall command them to wash the article in which the disease appears, and he shall put it aside for seven days more. ⁵⁵ The priest shall examine the diseased article after it has been washed. If the diseased spot has not changed colour, though the disease has not spread, it is unclean; you shall burn it in fire, whether the leprous^[a] spot is on the inside or on the outside.

⁵⁶ If the priest makes an examination, and the disease has abated after it is washed, he shall tear the spot out of the cloth, in warp or woof, or out of skin.
