Leviticus 13:15-17

Amplified Bible

¹⁵ The priest shall examine the raw flesh, and he shall pronounce him unclean; the raw flesh is unclean, it is leprosy. ¹⁶ But if the raw flesh turns again and is changed to white, then he shall come to the priest, ¹⁷ and the priest shall examine him, and if the diseased part is changed to white, then the priest shall pronounce him who had the disease to be clean; he is clean.
