Leviticus 13:9–28

⁹“When a person contracts a defiling skin disease, he shall be brought to the priest. ¹⁰The priest shall make an examination, and if there is a white swelling^k in the skin that has turned the hair white and there is a patch of raw flesh in the swelling,^{l* 11}it is a chronic defiling disease in the skin of his body. The priest shall pronounce him unclean; he shall not confine him, for he is unclean. ¹²But if the defiling disease breaks out in the skin so that it covers all the skin of the diseased person from head to foot, so far as the priest can see, ¹³then the priest shall make an examination, and if the defiling disease has covered all his body, he shall pronounce him clean of the disease; since it has all turned white, he is clean. ¹⁴But if raw flesh ever appears on him, he shall be unclean; ¹⁵the priest shall examine the raw flesh and pronounce him unclean. Raw flesh is unclean; it is defiling.^{* 16}But if the raw flesh again turns white, he shall come to the priest;^{* 17}the priest shall examine him, and if the disease has turned white, the priest shall pronounce the diseased person clean. He is clean.

¹⁸“When there is on the skin of one’s body a boil that has healed,^{* 19}and in the place of the boil there appears a white swelling^m or a reddish-white spot, it shall be shown to the priest.^{* 20}The priest shall make an examination, and if it appears deeper than the skin and its hair has turned white, the priest shall pronounce him unclean; this is a defiling disease, broken out in the boil. ²¹But if the priest examines it and the hair on it is not white nor is it deeper than the skin but has abated, the priest shall confine him seven days.^{* 22}If it spreads in the skin, the priest shall pronounce him unclean; it is diseased. ²³But if the spot remains in one place and does not spread, it is the scar of the boil; the priest shall pronounce him clean.

²⁴“Or when the body has a burn on the skin and the patch of the burn becomes a spot, reddish-white or white, ²⁵the priest shall examine it. If the hair in the spot has turned white and appears deeper than the skin, it is defiling; it has broken out in the burn, and the priest shall pronounce him unclean. This is a defiling disease.^{* 26}But if the priest examines it and the hair in the spot is not white and it is no deeper than the skin but has abated, the priest shall confine him seven days. ²⁷The priest shall examine him the seventh day; if it is spreading in the skin, the priest shall pronounce him unclean. This is a defiling disease.^{* 28}But if the spot remains in one place and does not spread in the skin but has abated, it is a swellingⁿ from the burn, and the priest shall pronounce him clean, for it is the scar of the burn.
