Leviticus 13:18–28

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.
