Leviticus 13:18-23

New King James Version

¹⁸ “If the body develops a ^(A)boil in the skin, and it is healed, ¹⁹ and in the place of the boil there comes a white swelling or a bright spot, reddish-white, then it shall be shown to the priest; ²⁰ and if, when the priest sees it, it indeed appears deeper than the skin, and its hair has turned white, the priest shall pronounce him unclean. It is a leprous sore which has broken out of the boil. ²¹ But if the priest examines it, and indeed there are no white hairs in it, and it is not deeper than the skin, but has faded, then the priest shall isolate him seven days; ²² and if it should at all spread over the skin, then the priest shall pronounce him unclean. It is a ^[a]leprous sore. ²³ But if the bright spot stays in one place, and has not spread, it is the scar of the boil; and the priest shall pronounce him clean.
