Vayikra 13:4-6

Orthodox Jewish Bible

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;

⁶ And the kohen shall examine him again on the yom hashevi’i; and, hinei, if the nega be somewhat faded, and the nega spread not in the skin, the kohen shall pronounce him tahor; it is but a scab; and he shall wash his clothes, and be tahor.
