Leviticus 13:2–8

2 “When a man has on the skin of his 1body a swelling or a scab or a bright spot, and it becomes 2an infection of leprosy on the skin of his 1body, athen he shall be brought to Aaron the priest or to one of his sons the priests.

3 “The priest shall look at the mark on the skin of the 1body, and if the hair in the infection has turned white and the infection appears to be deeper than the skin of his 1body, it is an infection of leprosy; when the priest has looked at him, he shall pronounce him unclean.

4 “But if the bright spot is white on the skin of his 1body, and 2it does not appear to be deeper than the skin, and the hair on it has not turned white, then the priest shall 3isolate him who has the infection for seven days.

5 “The priest shall look at him on the seventh day, and if in his eyes the infection 1has not changed and the infection has not spread on the skin, then the priest shall 2isolate him for seven more days.

6 “The priest shall look at him again on the seventh day, and if the infection has faded and the mark has not spread on the skin, then the priest shall pronounce him clean; it is only a scab. And he shall awash his clothes and be clean.

7 “But if the scab spreads farther on the skin after he has shown himself to the priest for his cleansing, he shall appear again to the priest.

8 “The priest shall look, and if the scab has spread on the skin, then the priest shall pronounce him unclean; it is leprosy.
