Leviticus 13:42-44

42But if on the bald head or the bald forehead, there occurs a reddish-white infection, it is leprosy breaking out on his bald head or on his bald forehead. 43Then 1the priest shall look at him; and if the swelling of the infection is reddish-white on his bald head or on his bald forehead, like the appearance of leprosy in the skin of the 2body, 44he is a leprous man, he is unclean. The priest shall surely pronounce him unclean; his infection is on his head.
