Leviticus 13:7-9

New Living Translation

⁷ But if the rash continues to spread after the person has been examined by the priest and has been pronounced clean, the infected person must return to be examined again. ⁸ If the priest finds that the rash has spread, he must pronounce the person ceremonially unclean, for it is indeed a skin disease.

⁹ “Anyone who develops a serious skin disease must go to the priest for an examination.
