Leviticus 13:3-5

Darby Translation

³ And when the priest looketh on the sore in the skin of the flesh, and the hair in the sore is turned white, and the sore looketh deeper than the skin of his flesh, it is the sore of leprosy; and the priest shall look on him and pronounce him unclean.

⁴ But if the bright spot be white in the skin of his flesh, and look not deeper than the skin, and the hair thereof be not turned white, the priest shall shut up [him that hath] the sore seven days.

⁵ And the priest shall look on him the seventh day; and behold, in his sight, the sore remaineth as it was, the sore hath not spread in the skin, then the priest shall shut him up seven days a second time.
