18When a boil appears on someone’s skin and it heals,
19and a white swelling or a reddish-white spot develops where the boil was, he must present himself to the priest.
20The priest shall examine it, and if it appears to be beneath the skin and the hair in it has turned white, the priest shall pronounce him unclean; it is a diseased infection that has broken out in the boil.
21But when the priest examines it, if there is no white hair in it, and it is not beneath the skin and has faded, the priest shall isolate him for seven days.
22If it spreads any further on the skin, the priest must pronounce him unclean; it is an infection.
23But if the spot remains unchanged and does not spread, it is only the scar from the boil, and the priest shall pronounce him clean.
