Leviticus 13:11-13

Amplified Bible

¹¹ it is a chronic leprosy on the skin of his body, and the priest shall pronounce him unclean; he shall not isolate him because he is [clearly] unclean. ¹² But if the [suspected] leprosy breaks out farther on the skin, and it covers all of the skin of the one who has the outbreak—from his head to his foot—wherever the priest looks, ¹³ the priest shall examine him. If the [suspected] leprosy has covered his entire body, he shall pronounce him clean of the disease; it has all turned white, and he is clean.
