Leviticus 13:34-36

New Revised Standard Version Catholic Edition

³⁴ On the seventh day the priest shall examine the itch; if the itch has not spread in the skin and it appears to be no deeper than the skin, the priest shall pronounce him clean. He shall wash his clothes and be clean. ³⁵ But if the itch spreads in the skin after he was pronounced clean, ³⁶ the priest shall examine him. If the itch has spread in the skin, the priest need not seek for the yellow hair; he is unclean.
