Leviticus 13:13-15

New King James Version

¹³ then the priest shall consider; and indeed if the leprosy has covered all his body, he shall pronounce him clean who has the sore. It has all turned ^(A)white. He is clean. ¹⁴ But when raw flesh appears on him, he shall be unclean. ¹⁵ And the priest shall examine the raw flesh and pronounce him to be unclean; for the raw flesh is unclean. It is leprosy.
