24 "When someone has a burn on his skin and a reddish-white or white spot appears in the raw flesh of the burn,
25 the priest is to examine the spot, and if the hair in it has turned white, and it appears to be more than skin deep, it is an infectious disease that has broken out in the burn. The priest shall pronounce him unclean; it is an infectious skin disease.1
