Leviticus 13:39-44

³⁹then the priest shall look; and, behold, if the bright spots in the skin of their flesh be of a dull white, it is a tetter, it hath broken out in the skin: he is clean.

⁴⁰And if a man's hair be fallen off his head, he is bald; yet is he clean.

⁴¹And if his hair be fallen off from the front part of his head, he is forehead-bald; yet is he clean.

⁴²But if there be in the bald head, or the bald forehead, a reddish-white plague, it is leprosy breaking out in his bald head, or his bald forehead.

⁴³Then the priest shall look upon him; and, behold, if the rising of the plague be reddish-white in his bald head, or in his bald forehead, as the appearance of leprosy in the skin of the flesh,

⁴⁴he is a leprous man, he is unclean; the priest shall surely pronounce him unclean: his plague is in his head.
