Leviticus 13:1-14

1Then the Lord spoke to Moses and to Aaron, saying, 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 3body, 4then he shall be brought to Aaron the priest or to one of his sons the priests. 3The priest shall look at the mark on the skin of the 5body, and if the hair in the infection has turned white and the infection appears to be deeper than the skin of his 6body, it is an infection of leprosy; when the priest has looked at him, he shall pronounce him unclean. 4But if the bright spot is white on the skin of his 7body, and 8it does not appear to be deeper than the skin, and the hair on it has not turned white, then the priest shall 9isolate him who has the infection for seven days. 5The priest shall look at him on the seventh day, and if in his eyes the infection 10has not changed and the infection has not spread on the skin, then the priest shall 11isolate him for seven more days. 6The 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 12wash 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. 8The priest shall look, and if the scab has spread on the skin, then the priest shall pronounce him unclean; it is leprosy.

9“When the infection of leprosy is on a man, then he shall be brought to the priest. 10The priest shall then look, and if there is a 13white swelling in the skin, and it has turned the hair white, and there is quick raw flesh in the swelling, 11it is 14a chronic leprosy on the skin of his 15body, and the priest shall pronounce him unclean; he shall not 16isolate him, for he is unclean. 12If the leprosy breaks out farther on the skin, and the leprosy covers all the skin of him who has the infection from his head even to his feet, 17as far as the priest can see, 13then the priest shall look, and behold, if the leprosy has covered all his 18body, he shall pronounce clean him who has the infection; it has all turned white and he is clean. 14But whenever raw flesh appears on him, he shall be unclean.
