Leviticus 13:40-44

40“When a man’s head is bare so that he is balding in back, he is clean.

41If his head is bare on the forehead so that he is balding in front, he is clean.

42But if there is a reddish white infection in the back or front bald area, it is a disease breaking out in his back or front bald area.

43The priest is to examine it, and if the swelling of the infection is reddish white in the back or front bald area like the appearance of a disease on the skin of the body,

44he is a diseased man. He is unclean. The priest must surely pronounce him unclean because of his infection on his head.
