7 But if the sore spreads after the priest has examined you and pronounced you clean, you must appear before the priest again.
8 The priest will examine you again, and if it has spread, he shall pronounce you unclean; it is a dreaded skin disease.
9 If any of you have a dreaded skin disease, you shall be brought to the priest,
10 who will examine you. If there is a white sore on your skin which turns the hairs white and is full of pus,
11 it is a chronic skin disease. The priest shall pronounce you unclean; there is no need to isolate you, because you are obviously unclean.
12 If the skin disease spreads and covers you from head to foot,
13 the priest shall examine you again. If he finds that it actually has covered the whole body, he shall pronounce you ritually clean. If your whole skin has turned white, you are ritually clean.
