Leviticus 13:9–28

⁹“If anyone has an infectious skin disease, he must be taken to the priest. ¹⁰The priest will examine him. If there is a white sore that has turned the hair white, and if there is raw flesh in the sore, ¹¹he has a chronic skin disease. Without putting him in isolation, the priest must declare him unclean because he is unclean. ¹²If skin disease develops and covers the whole person from head to foot (so far as the priest can see), ¹³the priest will examine him. If the disease does cover his whole body, the priest must declare the diseased person clean. His body has turned white. The person is clean. ¹⁴But if raw flesh appears, he will be unclean. ¹⁵The priest will examine the raw flesh and declare him unclean. The raw flesh is unclean. It is an infectious skin disease. ¹⁶But if the raw flesh turns white again, he must go to the priest. ¹⁷The priest will examine him again, and if the diseased area has turned white, the priest must declare the diseased person clean. He is clean. 

¹⁸“If a boil on the skin has healed ¹⁹and in its place there is a white sore or a pink area, it must be shown to the priest. ²⁰The priest will examine it. If it looks deeper than the rest of the skin and its hair has turned white, the priest must declare the person unclean. An infectious skin disease has developed in the boil. ²¹But if the priest examines the affected area and the hair in it is not white or the affected area is not deeper than the rest of the skin but has faded, the priest must put him in isolation for seven days. ²²If the area has spread, the priest must declare him unclean. It is a skin disease. ²³But if the irritated area has not spread, it is a scar caused by the boil. The priest must declare him clean. 

²⁴“If anyone has a burn on his skin and the raw flesh of the burn turns into a pink or bright white area, ²⁵the priest will examine it. If the hair on the affected area has turned white and the affected area looks deeper than the rest of the skin, an infectious skin disease has developed in the burn. The priest must declare him unclean. It is an infectious skin disease. ²⁶But if the priest examines it and the hair in it is not white and the affected area is not deeper than the rest of the skin but has faded, the priest must put him in isolation for seven days. ²⁷On the seventh day the priest will examine him again. If the area has spread, the priest must declare him unclean. It is an infectious skin disease. ²⁸If the irritated area does not spread but has faded, it is only a sore caused by the burn. The priest must declare him clean, because it is a scar caused by the burn.
