Leviticus 13:15-17

New King James Version

¹⁵ And the priest shall examine the raw flesh and pronounce him to be unclean; for the raw flesh is unclean. It is leprosy. ¹⁶ Or if the raw flesh changes and turns white again, he shall come to the priest. ¹⁷ And the priest shall examine him; and indeed if the sore has turned white, then the priest shall pronounce him clean who has the sore. He is clean.
