Leviticus 13:5-7

New King James Version

⁵ And the priest shall examine him on the seventh day; and indeed if the sore appears to be as it was, and the sore has not spread on the skin, then the priest shall isolate him another seven days. ⁶ Then the priest shall examine him again on the seventh day; and indeed if the sore has faded, and the sore has not spread on the skin, then the priest shall pronounce him clean; it is only a scab, and he ^(A)shall wash his clothes and be clean. ⁷ But if the scab should at all spread over the skin, after he has been seen by the priest for his cleansing, he shall be seen by the priest again.
