Leviticus 13:39-44

³⁹then the priest must examine the person to see if the spots are a dull white, which is only a rash that has broken out in the skin. He is clean.

⁴⁰If a man's hair has fallen out of his head, he is bald, but he is clean.

⁴¹If his hair has fallen out of the front part of his head, and if his forehead is bald, he is clean.

⁴²But if there is a reddish-white sore on his bald head or forehead, it is an infectious disease that has broken out.

⁴³Then the priest must examine him to see if the swelling of the diseased area on his bald head or forehead is reddish-white, like the appearance of an infectious disease in the skin.

⁴⁴If it is, then he has an infectious disease and he is unclean. The priest must surely pronounce him unclean because of his disease on his head.
