Leviticus 13:39-44

³⁹and the priest look, and behold, there are in the skin of their flesh pale white spots, it is an eruption which is broken out in the skin: he is clean.

⁴⁰And if a man's hair have fallen off his head, he is bald: he is clean;

⁴¹and if he have the hair fallen off from the part of the head towards his face, he is forehead-bald: he is clean.

⁴²And if there be in the bald head, or bald forehead, a white-reddish sore, it is a leprosy which hath broken out in his bald head, or his bald forehead.

⁴³And the priest shall look on it, and behold, the rising of the sore is white-reddish in his bald head, or in his bald forehead, like the appearance of the leprosy in the skin of the flesh;

⁴⁴he is a leprous man, he is unclean; the priest shall pronounce him utterly unclean; his sore is in his head.
