Leviticus 13:13-15

New Catholic Bible

¹³ then the priest shall examine the person whose flesh is covered with leprosy. He shall declare him clean when it has all turned white, for he is clean. ¹⁴ But when some raw skin appears on him, he shall be held to be unclean. ¹⁵ The priest, when he sees the raw skin, shall declare him unclean. The raw skin is unclean; it is leprosy.
