Leviticus 13:12-14

New Catholic Bible

¹² If the leprosy breaks out upon the skin so that the leprosy covers all of the skin of the diseased person wherever the priest examined him, from head to foot, 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.
