1-3. God spoke to Moses and Aaron: “When someone has a swelling or a blister or a shiny spot on the skin that might signal a serious skin disease on the body, bring him to Aaron the priest or to one of his priest sons. The priest will examine the sore on the skin. If the hair in the sore has turned white and the sore appears more than skin deep, it is a serious skin disease and infectious. After the priest has examined it, he will pronounce the person unclean.
18-23. “When a person has a boil and it heals and in place of the boil there is white swelling or a reddish-white shiny spot, the person must present himself to the priest for an examination. If it looks like it has penetrated the skin and the hair in it has turned white, the priest will pronounce him unclean. It is a serious skin disease that has broken out in the boil. But if the examination shows that there is no white hair in it and it is only skin deep and has faded, the priest will put him in quarantine for seven days. If it then spreads over the skin, the priest will diagnose him as unclean. It is infectious. But if the shiny spot has not changed and hasn’t spread, it’s only a scar from the boil. The priest will pronounce him clean.
24-28. “When a person has a burn on his skin and the raw flesh turns into a reddish-white or white shiny spot, the priest is to examine it. If the hair has turned white in the shiny spot and it looks like it’s more than skin deep, a serious skin disease has erupted in the area of the burn. The priest will pronounce him unclean; it is a serious skin disease and infectious. But if on examination there is no white hair in the shiny spot and it doesn’t look to be more than skin deep but has faded, the priest will put him in quarantine for seven days. On the seventh day the priest will reexamine him. If by then it has spread over the skin, the priest will diagnose him as unclean; it is a serious skin disease and infectious. If by that time the shiny spot has stayed the same and has not spread but has faded, it is only a swelling from the burn. The priest will pronounce him clean; it’s only a scar from the burn.
29-37. “If a man or woman develops a sore on the head or chin, the priest will offer a diagnosis. If it looks as if it is under the skin and the hair in it is yellow and thin, he will pronounce the person ritually unclean. It is an itch, an infectious skin disease. But if when he examines the itch, he finds it is only skin deep and there is no black hair in it, he will put the person in quarantine for seven days. On the seventh day he will reexamine the sore; if the itch has not spread, there is no yellow hair in it, and it looks as if the itch is only skin deep, the person must shave, except for the itch; the priest will send him back to quarantine for another seven days. If the itch has not spread, and looks to be only skin deep, the priest will pronounce him clean. The person can go home and wash his clothes; he is clean. But if the itch spreads after being pronounced clean, the priest must reexamine it; if the itch has spread in the skin, he doesn’t have to look any farther, for yellow hair, for instance; he is unclean. But if he sees that the itch is unchanged and black hair has begun to grow in it, the itch is healed. The person is clean and the priest will pronounce him clean.
