Leviticus 13:53-55

New American Standard Bible

⁵³ “But if the priest looks, and indeed the mark has not spread in the garment, either in the ^[a]warp or in the woof, or in any article of leather, ⁵⁴ then the priest shall order them to wash the thing in which the mark occurs, and he shall ^[b]quarantine it for seven more days. ⁵⁵ After the article with the mark has been washed, the priest shall again look, and if the mark has not changed its appearance, even if the mark has not spread, it is unclean; you shall burn it in the fire, whether an eating away has produced bareness on the back or on the front of it.
