1. The Lord gave Moses and Aaron these regulations.
2. If anyone has a sore on his skin or a boil or an inflammation which could develop into a dreaded skin disease, he shall be brought to the Aaronite priest.
3. The priest shall examine the sore, and if the hairs in it have turned white and the sore appears to be deeper than the surrounding skin, it is a dreaded skin disease, and the priest shall pronounce the person unclean.
4. But if the sore is white and does not appear to be deeper than the skin round it and the hairs have not turned white, the priest shall isolate the person for seven days.
5. The priest shall examine him again on the seventh day, and if in his opinion the sore looks the same and has not spread, he shall isolate him for another seven days.
6. The priest shall examine him again on the seventh day, and if the sore has faded and has not spread, he shall pronounce him ritually clean; it is only a sore. The person shall wash his clothes and be ritually clean.
7. But if the sore spreads after the priest has examined him and pronounced him clean, he must appear before the priest again.
8. The priest will examine him again, and if it has spread, he shall pronounce him unclean; it is a dreaded skin disease.
9. If anyone has a dreaded skin disease, he shall be brought to the priest,
10. who will examine him. If there is a white sore on his skin which turns the hairs white and is full of pus,
11. it is a chronic skin disease. The priest shall pronounce him unclean; there is no need to isolate him, because he is obviously unclean.
12. If the skin disease spreads and covers the person from head to foot,
13. the priest shall examine him again. If he finds that it actually has covered the whole body, he shall pronounce the person ritually clean. If his whole skin has turned white, he is ritually clean.
