Leviticus 13:41-44 New American Standard Bible (NASB)

41. If his head becomes bald at the front and sides, he is bald on the forehead; he is clean.

42. But 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.

43. Then the 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 body,

44. he is a leprous man, he is unclean. The priest shall surely pronounce him unclean; his infection is on his head.
