Leviticus 13
4 Ref If the bright spot is white in the skin of his body, and the appearance of it isn't deeper than the skin, and the hair of it hasn't turned white, then the priest shall isolate the infected person for seven days.
5 The priest shall examine him on the seventh day, and, behold, if in his eyes the plague is arrested, and the plague hasn't spread in the skin, then the priest shall isolate him for seven more days.
