Vayikra 13:3-5

Orthodox Jewish Bible

³ And the kohen shall examine the nega in the skin of the basar; and when hair in the nega is turned white, and the nega in appearance be deeper than the skin of his basar, it is a nega tzara’at; and the kohen shall examine him, and pronounce him tamei.

⁴ If the bright spot be white in the skin of his basar, and in appearance be not deeper than the skin, and the hair thereof be not turned white, then the kohen shall quarantine him that hath the nega shivat yamim;

⁵ And the kohen shall examine him on the yom hashevi’i; and, hinei, if the nega in his sight be unchanged, and the nega spread not in the skin; then the kohen shall quarantine him another shivat yamim;
